In the Linux kernel, the following vulnerability has been resolved: media: cec: Serialize exclusive follower delivery cec_receive_notify() reads the exclusive follower pointer without the adapter lock. Serialize the no-follower check and message delivery against mode changes and release.

ubuntu_linux USN-8959-1: Ubuntu 24.04 LTS / Ubuntu 26.04 LTS / Ubuntu Pro Realtime 24.04 LTS : Linux kernel vulnerabilities (USN-8959-1)

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8962-1 advisory.

    Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux     kernel, leading to use-after-free vulnerabilities. A local attacker could possibly use this to cause a     denial of service (system crash). (CVE-2022-1205)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

An update of the linux package has been released.

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1793100968 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: udf: Avoid double brelse() in     udf_rename() syzbot reported a warning like below [1]: VFS: brelse: Trying to free free buffer WARNING:
    CPU: 2 PID: 7301 at fs/buffer.c:1145 __brelse+0x67/0xa0 ...

    __x64_sys_exit_group+0x3a/0x50 do_syscall_64+0x34/0xb0 entry_SYSCALL_64_after_hwframe+0x63/0xcd The cause     of the issue is that brelse() is called on both ofibh.sbh and ofibh.ebh by udf_find_entry() when it     returns NULL. However, brelse() is called by udf_rename(), too. So, b_count on buffer_head becomes     unbalanced. This patch fixes the issue by not calling brelse() by udf_rename() when udf_find_entry()     returns NULL. (CVE-2022-50755)

  - In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmi_encdec: Restrict string     length in decode The QMI TLV value for strings in a lot of qmi element info structures account for null     terminated strings with MAX_LEN + 1. If a string is actually MAX_LEN + 1 length, this will cause an out of     bounds access when the NULL character is appended in decoding. (CVE-2023-53729)

  - In the Linux kernel, the following vulnerability has been resolved: can: isotp: check CAN address family     in isotp_bind() Add missing check to block non-AF_CAN binds. Syzbot created some code which matched the     right sockaddr struct size but used AF_XDP (0x2C) instead of AF_CAN (0x1D) in the address family field:
    bind$xdp(r2, &(0x7f0000000540)={0x2c, 0x0, r4, 0x0, r2}, 0x10) ^^^^ This has no funtional impact but the     userspace should be notified about the wrong address family field content. (CVE-2023-54105)

  - In the Linux kernel, the following vulnerability has been resolved: usb: rndis_host: Secure rndis_query     check against int overflow Variables off and len typed as uint32 in rndis_query function are controlled by     incoming RNDIS response message thus their value may be manipulated. Setting off to a unexpectetly large     value will cause the sum with len and 8 to overflow and pass the implemented validation step. Consequently     the response pointer will be referring to a location past the expected buffer boundaries allowing     information leakage e.g. via RNDIS_OID_802_3_PERMANENT_ADDRESS OID. (CVE-2023-54110)

  - In the Linux kernel, the following vulnerability has been resolved: mtd: spi-nor: Fix shift-out-of-bounds     in spi_nor_set_erase_type spi_nor_set_erase_type() was used either to set or to mask out an erase type.
    When we used it to mask out an erase type a shift-out-of-bounds was hit: UBSAN: shift-out-of-bounds in     drivers/mtd/spi-nor/core.c:2237:24 shift exponent 4294967295 is too large for 32-bit type 'int' The     setting of the size_{shift, mask} and of the opcode are unnecessary when the erase size is zero, as     throughout the code just the erase size is considered to determine whether an erase type is supported or     not. Setting the opcode to 0xFF was wrong too as nobody guarantees that 0xFF is an unused opcode. Thus     when masking out an erase type, just set the erase size to zero. This will fix the shift-out-of-bounds.

Consequently     the response pointer will be referring to a location past the expected buffer boundaries allowing     information leakage e.g. via RNDIS_OID_802_3_PERMANENT_ADDRESS OID. (CVE-2023-54110)

  - In the Linux kernel, the following vulnerability has been resolved: mtd: spi-nor: Fix shift-out-of-bounds     in spi_nor_set_erase_type spi_nor_set_erase_type() was used either to set or to mask out an erase type.
    When we used it to mask out an erase type a shift-out-of-bounds was hit: UBSAN: shift-out-of-bounds in     drivers/mtd/spi-nor/core.c:2237:24 shift exponent 4294967295 is too large for 32-bit type 'int' The     setting of the size_{shift, mask} and of the opcode are unnecessary when the erase size is zero, as     throughout the code just the erase size is considered to determine whether an erase type is supported or     not. Setting the opcode to 0xFF was wrong too as nobody guarantees that 0xFF is an unused opcode. Thus     when masking out an erase type, just set the erase size to zero. This will fix the shift-out-of-bounds.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - media: cec: Serialize exclusive follower delivery cec_receive_notify() reads the exclusive follower     pointer without the adapter lock. Serialize the no-follower check and message delivery against mode     changes and release. (CVE-2026-89897)

Note that Nessus relies on the presence of the package as reported by the vendor.
