Description OSIDB Bzimport 2025-12-30 13:03:16 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ext2: Add sanity checks for group and filesystem size

Add sanity check that filesystem size does not exceed the underlying
device size and that group size is big enough so that metadata can fit
into it. This avoid trying to mount some crafted filesystems with
extremely large group counts.
