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

  - f2fs: fix out-of-bounds access in sysfs attribute read/write Some f2fs sysfs attributes suffer from out-     of-bounds memory access and incorrect handling of integer values whose size is not 4 bytes. For example:
    vm:~# echo 65537 > /sys/fs/f2fs/vde/carve_out vm:~# cat /sys/fs/f2fs/vde/carve_out 65537 vm:~# echo     4294967297 > /sys/fs/f2fs/vde/atgc_age_threshold vm:~# cat /sys/fs/f2fs/vde/atgc_age_threshold 1 carve_out     maps to {struct f2fs_sb_info}->carve_out, which is a 8-bit integer. However, the sysfs interface allows     setting it to a value larger than 255, resulting in an out-of-range update. atgc_age_threshold maps to     {struct atgc_management}->age_threshold, which is a 64-bit integer, but its sysfs interface cannot     correctly set values larger than UINT_MAX. The root causes are: 1. __sbi_store() treats all default values     as unsigned int, which prevents updating integers larger than 4 bytes and causes out-of-bounds writes for     integers smaller than 4 bytes. 2. f2fs_sbi_show() also assumes all default values are unsigned int,     leading to out-of-bounds reads and incorrect access to integers larger than 4 bytes. This patch introduces     {struct f2fs_attr}->size to record the actual size of the integer associated with each sysfs attribute.
    With this information, sysfs read and write operations can correctly access and update values according to     their real data size, avoiding memory corruption and truncation. (CVE-2026-23235)
