medium Tenable Self-Hosted Container Security Plugin ID 464872

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to do sanity check on
 sit_bitmap_size w/ below testcase, resize will generate a corrupted image which contains inconsistent
 metadata, so when mounting such image, it will trigger kernel panic: touch img truncate -s
 $((512*1024*1024*1024)) img mkfs.f2fs -f img $((256*1024*1024)) resize.f2fs -s -i img -t

 do_syscall_64+0x82/0x190 entry_SYSCALL_64_after_hwframe+0x76/0x7e RIP: 0033:0x7fdbfde1bcfe The reaseon is:
 sit_i->bitmap_size is 192, so size of sit bitmap is 192*8=1536, at maximum there are 1536 sit blocks,
 however MAIN_SEGS is 261893, so that sit_blk_cnt is 4762, build_sit_entries() -> current_sit_addr() tries
 to access out-of-boundary in sit_bitmap at offset from [1536, 4762), once sit_bitmap and sit_bitmap_mirror
 is not the same, it will trigger f2fs_bug_on(). Let's add sanity check in f2fs_sanity_check_ckpt() to
 avoid panic. (CVE-2025-38218)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
