    2025-07-03: CVE-2023-53055 was added to this advisory.

    2025-06-19: CVE-2023-53080 was added to this advisory.

    2025-06-19: CVE-2023-53053 was added to this advisory.

    2025-06-19: CVE-2023-53058 was added to this advisory.

    2025-06-19: CVE-2023-53079 was added to this advisory.

    2025-06-19: CVE-2023-53051 was added to this advisory.

    2024-07-03: CVE-2023-1611 was added to this advisory.

    A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking     configuration (redirecting egress packets to ingress using TC action mirred) a local unprivileged user     could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a     retransmission, resulting in a denial of service condition. (CVE-2022-4269)

    A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel.
    This flaw allows an attacker to conduct a remote denial of service. (CVE-2022-4379)

    A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This     flaw allows an attacker to crash the system and possibly cause a kernel information lea (CVE-2023-1611)

    An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace data->block[0] variable was not capped to a number between 0-255 and was used as the size of a     memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

    In the Linux kernel, the following vulnerability has been resolved:

    dm crypt: add cond_resched() to dmcrypt_write() (CVE-2023-53051)

    In the Linux kernel, the following vulnerability has been resolved:

    erspan: do not use skb_mac_header() in ndo_start_xmit() (CVE-2023-53053)

    In the Linux kernel, the following vulnerability has been resolved:

    fscrypt: destroy keyring after security_sb_delete() (CVE-2023-53055)

    In the Linux kernel, the following vulnerability has been resolved:

    net/mlx5: E-Switch, Fix an Oops in error handling code (CVE-2023-53058)

    In the Linux kernel, the following vulnerability has been resolved:

    net/mlx5: Fix steering rules cleanup (CVE-2023-53079)

    In the Linux kernel, the following vulnerability has been resolved:

    xsk: Add missing overflow check in xdp_umem_reg (CVE-2023-53080)
