CVE-2024-41067

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the btrfs file system in the Linux kernel. When running btrfs/060 with the forced RST feature, it would crash due to an ASSERT() inside scrub read endio(). This happens because the btrfs map block() function fails, leading to an empty bio, which in turn causes the bvecs iteration to not find a matching sector, resulting in an ASSERT() trigger. The problem arises from calling btrfs map block() after allocating a new bbio. To fix this, btrfs map block() should be called first to update stripe len, avoiding the issue of handling empty bbio and a possible race window in the old code.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
