Description
No description is available for this CVE.
Statement
This patch does not directly fix an exploitable vulnerability but adds a diagnostic check to detect potential inode lifecycle races in ext4. If an inode marked as "no_delete" is dirtied while being evicted, it could theoretically lead to a use-after-free in writeback. In practice, this is extremely rare and hard to trigger, and the patch mainly improves robustness by ensuring such conditions are caught early with a warning.
