high Tenable Self-Hosted Container Security Plugin ID 470140

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: ext4: fix fast commit wait/wake bit
mapping on 64-bit On 64-bit, ext4 dynamic inode states live in the upper half of i_flags, and
ext4_test_inode_state() applies the corresponding +32 offset. The fast-commit wait and wake paths open-
coded the wait key with the raw EXT4_STATE_* value. Add small helpers for the state wait word and bit, and
use them for the FC_COMMITTING and FC_FLUSHING_DATA waits so the wait key follows the same mapping as the
state helpers. (CVE-2026-74358)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.21 or later.
