  - ocfs2: don't BUG_ON an invalid journal dinode [BUG] A fuzzed OCFS2 image can corrupt the current slot     journal dinode while mount is still in progress. The mount path first reports the invalid journal block     and then crashes in shutdown: kernel BUG at fs/ocfs2/journal.c:1034! Oops: invalid opcode: 0000 [#1] SMP     KASAN NOPTI RIP: 0010:ocfs2_journal_toggle_dirty+0x2d6/0x340 fs/ocfs2/journal.c:1034 Call Trace:

[CAUSE]     ocfs2_journal_toggle_dirty() used to return -EIO when journal->j_bh no longer contained a valid dinode,     because the startup and shutdown paths already handled that failure. Commit 10995aa2451a (ocfs2: Morph     the haphazard OCFS2_IS_VALID_DINODE() checks.) changed the check to a BUG_ON() under the assumption that     the journal dinode had already been validated. That turns an unexpected invalid journal dinode during     mount teardown into a kernel crash instead of a normal mount failure. [FIX] Replace the BUG_ON() with     WARN_ON() and return -EIO. This keeps the invariant warning for debugging, but restores the original     behavior of failing startup or shutdown cleanly instead of panicking the kernel. (CVE-2026-80644)

Note that Nessus relies on the presence of the package as reported by the vendor.
