Uninitialized memory disclosure in ws Node.js WebSocket library versions prior to 8.20.1 allows authenticated remote attackers with high privileges to extract server memory contents. Exploitation occurs when a TypedArray (other than Uint8Array) is passed to websocket.close() as the reason argument, causing the library to read and transmit uninitialized memory buffers. EPSS score not provided; no public exploit identified at time of analysis, but fix commit publicly available on GitHub.
Uninitialized kernel memory within AMD's Platform Management Framework (PMF) can be read by local authenticated attackers, resulting in information disclosure or availability impact. This affects AMD Ryzen processors across multiple generations (6000, 7035, 7040, 8040 series and Z1/Embedded 8000) where PMF is present. The vulnerability requires local access and authenticated user privileges but does not require user interaction, making it exploitable by any local user with login credentials.
Denial of service via uninitialized kernel memory in the Linux kernel's FUSE filesystem handler allows a local low-privileged user to crash the kernel by invoking the file_getattr syscall against a FUSE-mounted file. Affected are Linux kernel versions from the initial git history through stable branches predating the 6.18.19, 6.19.9, and 7.0 patch releases. No public exploit is identified at time of analysis, and EPSS sits at 0.02% (4th percentile), reflecting very low observed exploitation probability with no CISA KEV listing.
Improper error-path state management in the Linux kernel's unshare(2) syscall leaves calling processes with dangling filesystem root and working-directory pointers after partial namespace creation failure. When a local low-privileged process calls unshare() with both CLONE_NEWNS and CLONE_NEWCGROUP on an unshared fs_struct (users==1), a successful copy_mnt_ns() updates current->fs->root and current->fs->pwd into the new mount namespace before a subsequent copy_cgroup_ns() failure triggers cleanup - dissolving the mount tree while leaving those pointers referencing now-detached mounts. The calling process is stranded in a broken filesystem state, producing high availability impact (CVSS A:H) confined entirely to the calling process. No public exploit has been identified, EPSS is 0.02% (7th percentile), and this is not in CISA KEV, reflecting low real-world exploitation interest despite the bug existing since unshare(2) was first introduced.
Type confusion in the Linux kernel bonding driver allows local authenticated users to trigger kernel crashes and potentially escalate privileges when non-Ethernet devices (such as GRE tunnels) are enslaved to a bond interface. The vulnerability stems from bond_setup_by_slave() blindly copying header_ops from slave devices without accounting for device-specific private data structures, causing netdev_priv() in functions like ipgre_header() to access incorrect memory layouts. Vendor patches are available for kernel versions 6.12.78, 6.18.19, 6.19.9, and 7.0. EPSS exploitation probability is low (0.02%, 5th percentile) with no public exploit identified at time of analysis.
Integer signedness vulnerability in Linux kernel's Ceph networking library (libceph) allows remote attackers to trigger denial of service via crafted monitor map messages. The flaw enables bypassing memory allocation limits by exploiting signed/unsigned integer confusion in ceph_monmap_decode(), causing excessive memory allocation attempts that crash the system. With CVSS 7.5 (AV:N/AC:L/PR:N/UI:N) and 0.02% EPSS score, this represents a network-reachable DoS vector against systems using Ceph storage, though low exploitation probability suggests limited attacker interest. Patches available across all maintained kernel branches (5.15.203, 6.1.167, 6.6.130, 6.12.78, 6.18.19, 6.19.9, 7.0).
Use of uninitialized memory in Linux kernel f2fs filesystem node footer validation causes local denial of service. Linux kernel versions 7.0 through 7.1-rc1 with f2fs support allow local authenticated users to trigger a kernel crash by mounting a maliciously crafted f2fs filesystem image. The vulnerability occurs when f2fs_sanity_check_node_footer() accesses uninitialized folio data after a failed disk read operation during filesystem mount, as reported by syzbot. EPSS score of 0.02% (4th percentile) indicates minimal real-world exploitation likelihood. Vendor patches available for stable kernel branches 6.18.25, 7.0.2, and 7.1-rc1.
Improper packet data validation in Linux kernel NCI NFC subsystem breaks communication with NFC chips and creates potential for information disclosure. The vulnerability affects adjacent network attackers (AV:A) who can exploit variable-length packet handling without authentication (PR:N) to achieve high confidentiality impact, low integrity impact, and high availability impact. EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability despite CVSS 8.3 severity. Vendor patches available across multiple kernel versions (5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0) with upstream fixes committed to stable branches.
Local privilege escalation in Linux kernel ext4 filesystem causes kernel panic during mount operations when DOUBLE_CHECK is enabled. Affects multiple stable kernel versions from 6.6.128 through 7.0. The initialization race condition allows local authenticated users to trigger a denial of service by mounting specially crafted ext4 filesystems with corrupted block bitmaps. EPSS score of 0.02% (5th percentile) indicates low observed exploitation probability. Vendor patches available across all affected stable branches.
In the Linux kernel, the following vulnerability has been resolved: ipmi: ipmb: initialise event handler read bytes IPMB doesn't use i2c reads, but the handler needs to set a value. Otherwise an i2c read will return an uninitialised value from the bus driver.
