kernel: RDMA/rxe: Reject unknown opcodes before ICRC processing

A flaw was found in the Linux kernel's Soft RoCE RDMA/rxe driver. An unauthenticated remote attacker can send a specially crafted UDP packet with an unknown opcode to trigger an out-of-bounds read. This vulnerability can lead to a kernel panic, effectively causing a Denial of Service DoS on the...

kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable

A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...

kernel: dm cache policy smq: fix missing locks in invalidating cache blocks

A flaw was found in the Linux kernel's device-mapper dm cache policy, specifically within the smq module. In passthrough mode, the invalidatemapping operation lacks proper locking, allowing for concurrent access. This can lead to data races, resulting in data corruption or use-after-free issues,...

kernel: udf: fix partition descriptor append bookkeeping

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. A remote attacker could exploit this vulnerability by tricking a user into mounting a specially crafted UDF image containing repeated partition descriptors. This could lead to a heap out-of-bounds write, potentially...

kernel: zram: fix use-after-free in zram_bvec_write_partial()

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...

kernel: ip6_gre: Use cached t->net in ip6erspan_changelink()

A flaw was found in the Linux kernel's ip6gre module. An unprivileged user could exploit this vulnerability by migrating a network device, causing the ip6erspanchangelink function to incorrectly handle network namespace references. This error leads to a use-after-free condition when the original...

kernel: sctp: purge outqueue on stale COOKIE-ECHO handling

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. This vulnerability, a use-after-free, occurs when the system processes a Stale Cookie ERROR during the setup or reconfiguration of an SCTP association. A remote attacker could exploit this by sending...

kernel: net: qrtr: restrict socket creation to the initial network namespace

A flaw was found in the Linux kernel's QRTR Qualcomm IPC Router networking component. An unprivileged local attacker can create a QRTR socket in a separate network namespace. Due to improper handling of global state variables, this allows the attacker to send datagrams and control-plane messages ...

kernel: ALSA: 6fire: fix use-after-free on disconnect

A flaw was found in the Linux kernel's ALSA 6fire USB audio device driver. During the disconnection process of a 6fire USB audio device, a use-after-free vulnerability occurs. This happens when the system attempts to write to memory that has already been deallocated, which can lead to memory...

Important: Red Hat Security Advisory: kernel-rt security, bug fix, and enhancement update

An update for kernel-rt is now available for Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is...

kernel: ice: fix double-free of tx_buf skb

A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when icetso or icetxcsum functions fail, can lead to a double-free of a network buffer skb. This occurs because a transmit buffer txbuf may still point to an...

kernel: netfilter: conntrack: remove sprintf usage

A flaw was found in the Linux kernel's netfilter conntrack module. This vulnerability arises from the use of sprintf and insufficient buffer sizing in the manglecontentlen function, which can lead to a stack-out-of-bounds write. An attacker could potentially exploit this memory corruption issue t...
