WORM protection bypass in Samba's vfs_worm VFS module allows authenticated share users to defeat data retention controls by renaming a newly created file over an existing WORM-protected file. Affected users are those operating Samba deployments that have explicitly enabled the vfs_worm module for write-once, read-many data protection - such as compliance, archival, or audit log shares. An attacker with low-privilege write access can silently overwrite files that should be immutable post-grace-period, with high integrity impact (CVSS I:H). No public exploit or CISA KEV listing is identified at time of analysis.

Access control bypass in Samba allows authenticated SMB users who hold write permissions on the underlying filesystem to create or delete NTFS-style reparse point metadata on shares configured with 'read only = yes', defeating the read-only intent of the export. Because the necessary access checks are missing at the SMB layer, an attacker can change how files behave when accessed over SMB - for example, converting a regular file into a symbolic link or another reparse-point type - yielding an integrity and availability impact (CVSS 7.1). There is no public exploit identified at time of analysis, and CISA's SSVC framework rates exploitation as 'none', non-automatable, with partial technical impact.

Trust-store poisoning in Samba's certificate auto-enrollment lets an adjacent-network attacker install an attacker-controlled CA certificate when auto-enrollment is enabled. Because Samba retrieves the CA certificate over plaintext HTTP and adds it to the local trust store without verifying authenticity, a man-in-the-middle can have a rogue CA trusted system-wide, enabling interception or spoofing of otherwise trusted TLS communications. The issue carries CVSS 8.0 with high confidentiality and integrity impact and a changed scope; EPSS is 0.00% and no public exploit identified at time of analysis.

Heap-based buffer overflow in libsolv's repo_add_solv() function enables a remote unauthenticated attacker to crash the parsing process by delivering a specially crafted .solv repository metadata file containing negative values in the maxsize or allsize header fields. The malformed values bypass allocation sizing logic, producing an undersized heap buffer that is subsequently written past its bounds, yielding a denial of service. No public exploit identified at time of analysis; however, an upstream fix has been submitted via openSUSE/libsolv GitHub PR #617, and Red Hat has acknowledged the issue via a dedicated security advisory.

Stack-based buffer overflow in libsolv's Debian metadata parser allows remote, unauthenticated attackers to cause a denial of service by serving maliciously crafted Debian repository metadata containing SHA384 or SHA512 checksum tags. The root cause, confirmed by the GitHub PR #616 diff, is a statically allocated 65-byte stack buffer in `ext/repo_deb.c` sized only for SHA256 digests, which is overflowed by the larger SHA384 (96 hex chars) and SHA512 (128 hex chars) values. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis; an upstream fix is available as an open pull request.

Denial of service in GnuTLS affects the Datagram Transport Layer Security (DTLS) packet reordering logic, where the comparator function fails to correctly handle packets with duplicate sequence numbers. Remote unauthenticated attackers can send specially crafted DTLS packet sequences to trigger unstable ordering or undefined behavior, causing service disruption. No public exploit identified at time of analysis, and the issue is rated CVSS 7.5 (High) for availability impact only.

Authentication bypass in GnuTLS affects servers that enable the RSA-PSK key exchange, where the PSK identity comparison treats a username containing an embedded NUL byte as equal to a legitimate truncated username. Remote attackers can send a crafted username to circumvent pre-shared-key authentication and gain unauthorized access. There is no public exploit identified at time of analysis, the EPSS probability is low (0.15%), and CISA SSVC scores exploitation as none - indicating high theoretical severity but no observed real-world abuse.

Polkit's polkit-agent-helper-1 setuid binary fails to bound input length on stdin, allowing local authenticated users to trigger out-of-memory conditions and deny system availability. An attacker with local login privileges can supply excessively long input to exhaust memory resources, causing a system-wide denial of service. No public exploit code or active exploitation has been confirmed at the time of analysis.

Libarchive fails to properly validate the pz_log2_bs field in ISO9660 Rock Ridge extensions during zisofs decompression, allowing remote attackers to supply a crafted ISO file that triggers undefined behavior and causes denial-of-service through incorrect memory allocation and application crashes. The vulnerability requires user interaction (ISO file opening) but no authentication, affects libarchive across multiple distributions, and carries a moderate EPSS score (0.11%, 30th percentile) suggesting low current exploitation probability despite the moderate CVSS severity.

A vulnerability was recently discovered in the rpc.mountd daemon in the nfs-utils package for Linux, that allows a NFSv3 client to escalate the privileges assigned to it in the /etc/exports file at mount time. [CVSS 6.5 MEDIUM]

A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. [CVSS 2.9 LOW]

libxml2's xmlCatalogXMLResolveURI function is vulnerable to uncontrolled recursion when processing self-referencing delegate URI entries in XML catalogs, allowing remote attackers to trigger stack exhaustion and crash applications. This configuration-dependent denial of service requires specially crafted XML input but no authentication, affecting any application using the vulnerable library to parse untrusted catalogs. No patch is currently available.

A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. [CVSS 3.7 LOW]

Heap-based buffer overflow in GLib's g_escape_uri_string() function allows local attackers to achieve high-integrity and high-availability impacts through integer overflow in escaped string length calculation. The vulnerability affects Red Hat Enterprise Linux 9.0 and 10.0 across multiple architectures (x86_64, ARM64, IBM Z, PowerPC). Vendor patches are available via multiple RHSA advisories. Publicly available exploit code exists, but EPSS score remains extremely low (0.01%, 1st percentile), suggesting minimal real-world exploitation activity despite the availability of technical details.

DNS resolve confusion in netavark, the Rust-based network stack for Podman containers, causes container name lookups to be forwarded to unexpected external DNS servers due to a regression that removed the dns.podman search domain. Affected deployments on Red Hat Enterprise Linux 8/9/10 and OpenShift Container Platform 4.0 running netavark < 1.15.1 are subject to misdirected container DNS resolution when host resolv.conf search domains contain a record matching a running container's hostname. The impact is limited to information disclosure (CVSS 3.7, Low), with no confirmed active exploitation and no public exploit identified at time of analysis.

A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, an out-of-bounds write can be triggered. This issue can lead to a crash or other unexpected behavior, and arbitrary code execution is not discarded. To exploit this flaw, a high-privilege account is needed as it's required to place the malicious policy file properly.

CVE-2025-7424 is a type confusion vulnerability in the libxslt library where the psvi (Post-Schema-Validation Infoset) memory field is reused for both stylesheet and input document processing, enabling memory corruption during XML transformations. This affects any application using vulnerable libxslt versions to process untrusted XML stylesheets or documents, allowing unauthenticated remote attackers to trigger denial of service or memory corruption without requiring user interaction. The vulnerability has a high CVSS score (7.5) with high availability impact, though real-world exploitation probability and active KEV status require confirmation from official sources.

A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.

A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly.

Memory corruption and denial of service in GnuTLS arises from a double-free (CWE-415) in the code that exports X.509 Subject Alternative Name entries containing an otherName field. When the type-id OID inside such an entry is invalid or malformed, GnuTLS calls asn1_delete_structure() on an ASN.1 node it does not own, so the same structure is freed again by the calling function, corrupting allocator state. The flaw is reachable through public GnuTLS APIs - meaning any application that parses or re-exports an attacker-supplied certificate is exposed - and there is no public exploit identified at time of analysis (EPSS 0.04%, 12th percentile; not in CISA KEV).

A security vulnerability in A flaw (CVSS 6.5). Remediation should follow standard vulnerability management procedures.

Cryptographic key derivation failure in libssh versions prior to 0.11.2 (when built against OpenSSL older than 3.0) can cause SSH sessions to proceed with uninitialized key material, allowing remote attackers to undermine session confidentiality and integrity. The flaw stems from inverted return-value semantics between OpenSSL and libssh in ssh_kdf(), so a silent KDF failure is treated as success. No public exploit identified at time of analysis and EPSS risk is low (0.07%), but the issue is widely shipped across Red Hat, Ubuntu, Debian and SUSE distributions and has vendor patches available.

CVE-2025-5318 is an out-of-bounds read vulnerability in libssh versions before 0.11.2 caused by an incorrect comparison check in the sftp_handle function that allows authenticated remote attackers to access memory beyond the valid handle list and retrieve invalid pointers for further processing. This vulnerability enables exposure of sensitive information or denial of service, with a CVSS score of 8.1 indicating high severity. The vulnerability requires authentication and network access but has high confidentiality and availability impact.

A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files.

Stack-based buffer overflow in libxml2's xmlBuildQName function allows remote unauthenticated attackers to crash affected systems via crafted XML input. The vulnerability affects libxml2 directly and downstream Red Hat products including OpenShift Container Platform 4.12-4.19, RHEL 7-10, and JBoss Core Services. With CVSS 7.5 (AV:N/AC:L/PR:N/UI:N), EPSS 0.75% (73rd percentile), and publicly available exploit code, this represents a moderate real-world risk focused on availability disruption rather than code execution or data compromise.

A vulnerability has been identified in the libarchive library. This flaw can be triggered when file streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-bounds read can lead to unintended consequences, including unpredictable program behavior, memory corruption, or a denial-of-service condition.

A vulnerability has been identified in the libarchive library. This flaw involves an 'off-by-one' miscalculation when handling prefixes and suffixes for file names. This can lead to a 1-byte write overflow. While seemingly small, such an overflow can corrupt adjacent memory, leading to unpredictable program behavior, crashes, or in specific circumstances, could be leveraged as a building block for more sophisticated exploitation. This bug affects libarchive versions prior to 3.8.0.

A vulnerability has been identified in the libarchive library. This flaw involves an integer overflow that can be triggered when processing a Web Archive (WARC) file that claims to have more than INT64_MAX - 4 content bytes. An attacker could craft a malicious WARC archive to induce this overflow, potentially leading to unpredictable program behavior, memory corruption, or a denial-of-service condition within applications that process such archives using libarchive. This bug affects libarchive versions prior to 3.8.0.

A vulnerability has been identified in the libarchive library. This flaw can lead to a heap buffer over-read due to the size of a filter block potentially exceeding the Lempel-Ziv-Storer-Schieber (LZSS) window. This means the library may attempt to read beyond the allocated memory buffer, which can result in unpredictable program behavior, crashes (denial of service), or the disclosure of sensitive information from adjacent memory regions.

CVE-2025-5914 is an integer overflow vulnerability in libarchive's archive_read_format_rar_seek_data() function that leads to a double-free memory corruption condition. This affects all users of libarchive who process untrusted RAR archive files, potentially allowing arbitrary code execution or denial-of-service with user interaction (opening a malicious RAR file). While no KEV listing or confirmed public exploits are currently documented, the high CVSS score (7.8) and memory safety nature of the vulnerability indicate significant real-world risk if weaponized.

Arbitrary file write outside the intended destination in rsync's client-side `--safe-links` handling allows a malicious or compromised rsync server to bypass the symlink safety check via a path-traversal flaw (CWE-22). The client fails to recursively verify whether a symbolic-link target supplied by the server itself contains a nested symlink, so a controlled server can place files anywhere the rsync process can write. A detailed advisory was published by Google's security-research team (GHSA-p5pg-x43v-mvqj) as part of the January 2025 rsync vulnerability cluster, but the issue is not in CISA KEV and no public exploit identified at time of analysis; EPSS is moderate at 2.89% (86th percentile).
