Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 465231

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: protect extension_list reading
with sb_lock in f2fs_sbi_show() In f2fs_sbi_show(), the extension_list, extension_count and hot_ext_count
are read without holding sbi->sb_lock. If a concurrent sysfs store modifies the extension list via
f2fs_update_extension_list(), the show path may read inconsistent count and array contents, potentially
leading to out-of-bounds access or displaying stale data. Fix this by holding sb_lock around the entire
extension list read and format operation. (CVE-2026-53303)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
