Description OSIDB Bzimport 2025-06-18 12:11:28 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ext4: avoid resizing to a partial cluster size

This patch avoids an attempt to resize the filesystem to an
unaligned cluster boundary.  An online resize to a size that is not
integral to cluster size results in the last iteration attempting to
grow the fs by a negative amount, which trips a BUG_ON and leaves the fs
with a corrupted in-memory superblock.
