Published Oct 21, 2024

In the Linux kernel, the following vulnerability has been resolved:

ext4: avoid OOB when system.data xattr changes underneath the filesystem

When looking up for an entry in an inlined directory, if evalueoffs is changed underneath the filesystem by some change in the block device, it will lead to an out-of-bounds access that KASAN detects as an UAF.

EXT4-fs (loop0): mounted filesystem 00000000-0000-0000-0000-000000000000 r/w without journal.

Calling ext4xattribodyfind right after reading the inode with ext4getinodeloc will lead to a check of the validity of the xattrs, avoiding this problem.
