CVE-2025-40101

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

Description A memory leak issue was addressed in the Linux kernel related to the btrfs filesystem. Specifically, the issue occurs when rejecting a non-SINGLE data profile without a RAID stripe tree (RST). The btrfs load block group zone info() function fails to free allocated memory in certain scenarios, leading to memory leaks. The fix involves ensuring that cleanup code is executed even when returning early due to an invalid data profile.

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