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]
IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 nimsh service SSL/TLS implementations could allow a remote attacker to execute arbitrary commands due to improper process controls. Rated critical severity (CVSS 9.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 NIM server (formerly known as NIM master) service (nimesis) could allow a remote attacker to execute arbitrary commands due to improper process. Rated critical severity (CVSS 10.0), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 NIM server (formerly known as NIM master) service (nimesis) could allow a remote attacker to traverse directories on the system. Rated high severity (CVSS 8.2), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
IBM AIX 7.2, and 7.3 and IBM VIOS 3.1, and 4.1 stores NIM private keys used in NIM environments in an insecure way which is susceptible to unauthorized access by an attacker using man in the middle. Rated critical severity (CVSS 9.0), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
Use-after-free memory corruption in X.Org X server's Xkb extension allows local authenticated attackers to achieve high confidentiality impact, low integrity impact, and high availability impact (CVSS 7.3) through improper resource cleanup during client disconnection. The vulnerability affects Red Hat Enterprise Linux distributions with multiple security advisories released (RHSA-2025:19432 through RHSA-2025:22055). EPSS data not provided, but the local attack vector (AV:L) and low complexity (AC:L) indicate exploitation requires authenticated local access. No CISA KEV listing or public POC identified at time of analysis.
Local privilege escalation in X.Org X server's Xkb extension affects RHEL-family distributions, allowing authenticated users to corrupt memory or crash the X server via integer overflow in XkbSetCompatMap(). Attack requires local access with low-privilege credentials. EPSS data not available; no CISA KEV listing indicates targeted rather than widespread exploitation. Red Hat has released patches across multiple RHEL versions (RHSA-2025:19432 through RHSA-2025:22055).
IBM AIX 7.2, 7.3, IBM VIOS 3.1, and 4.1, when configured to use Kerberos network authentication, could allow a local user to write to files on the system with root privileges due to improper. Rated high severity (CVSS 7.4), this vulnerability is no authentication required. No vendor patch available.
A vulnerability was found in libxml2 up to 2.14.5. Rated medium severity (CVSS 4.8), this vulnerability is low attack complexity. No vendor patch available.
Local privilege escalation vulnerability in IBM AIX 7.3 and IBM VIOS 4.1.1's Perl implementation that allows non-privileged local users to execute arbitrary code through improper pathname neutralization (path traversal). With a CVSS score of 8.4 and no authentication requirement, this represents a critical risk for AIX environments where local user access exists. The vulnerability's active exploitation status and proof-of-concept availability would significantly elevate real-world risk.
