VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to the ext4 component of the Linux kernel, specifically with the function ext4 mb find by goal() in fs/ext4/mballoc.c. It involves incorrect locking, which can lead to allocating blocks from a corrupted group. This can result in a denial of service. The logic for checking if the group's block bitmap is corrupt has been placed under the protection of the group lock to avoid this issue.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
