Echo: linux: security update to 6.1.180-1

high Tenable Self-Hosted Container Security Plugin ID 464942

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: validate orphan inode entry
 count f2fs_recover_orphan_inodes() trusts the orphan block entry_count when replaying orphan inodes from
 the checkpoint pack. A corrupted entry_count larger than F2FS_ORPHANS_PER_BLOCK makes the recovery loop
 read past the ino[] array and interpret footer or following data as inode numbers. On a crafted image,
 mounting an unpatched kernel can drive orphan recovery into f2fs_bug_on() and panic the kernel. Validate
 entry_count before consuming entries so corrupted checkpoint data fails the mount with -EFSCORRUPTED and
 requests fsck instead. Set ERROR_INCONSISTENT_ORPHAN as well, so the corruption reason can be recorded in
 the superblock s_errors[] field. This gives fsck a persistent hint even though mount-time orphan recovery
 failure may leave no chance to persist SBI_NEED_FSCK through a checkpoint. (CVE-2026-63818)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
