Description OSIDB Bzimport 2026-05-27 15:08:46 UTC
In the Linux kernel, the following vulnerability has been resolved:

ext4: drop extent cache when splitting extent fails

When the split extent fails, we might leave some extents still being
processed and return an error directly, which will result in stale
extent entries remaining in the extent status tree. So drop all of the
remaining potentially stale extents if the splitting fails.
