high Tenable Cloud Security Plugin ID 469462

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: jbd2: fix integer underflow in
jbd2_journal_initialize_fast_commit() jbd2_journal_initialize_fast_commit() validates journal capacity by
checking (journal->j_last - num_fc_blks < JBD2_MIN_JOURNAL_BLOCKS). Both j_last and num_fc_blks are
unsigned, so when num_fc_blks exceeds j_last the subtraction wraps to a large value, bypassing the bounds
check. The resulting underflow corrupts j_last, j_fc_first, and j_free, leading to journal abort. Fix by
checking num_fc_blks against j_last before the subtraction, returning -EFSCORRUPTED. (CVE-2026-72225)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.655.6 or later.
