- Summary
- ext4: remove a BUG_ON in ext4_mb_release_group_pa()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ext4: remove a BUGON in ext4mbreleasegroup_pa()
If a malicious fuzzer overwrites the ext4 superblock while it is mounted such that the sfirstdatablock is set to a very large number, the calculation of the block group can underflow, and trigger a BUGON check. Change this to be an ext4_warning so that we don't crash the kernel.
