CVE-2024-42306

CVE-2024-42306 – Linux kernel UDF vulnerability : The issue arises when a corrupted filesystem block bitmap can be inconsistently used for allocations due to bitmap buffer loading state, risking allocation failures or mixed results. The fix adds a BH_verified flag to track bitmap validity, ensuri...

CVE-2024-42306

In the Linux kernel, the following vulnerability has been resolved: udf: Avoid using corrupted block bitmap buffer When the filesystem block bitmap is corrupted, we detect the corruption while loading the bitmap and fail the allocation with error. However the next allocation from the same bitmap...
