In the Linux kernel, the following vulnerability has been resolved: ext4: fix double brelse the buffer of the extents path In ext4exttrytomergeup, set path1.pbh to NULL after it has been released, otherwise it may be released twice. An example of what triggers this is as follows: split2 map split...

CVE-2024-49881

In CVE-2024-49881, the Linux kernel ext4 caller path handling was fixed: in ext4_find_extent(), if a path is reallocated after being freed when depth exceeds path[0].p_maxdepth, orig_path was not updated, leaving the caller with a valid path but a NULL ppath. This could cause a NULL pointer deref...
