CVE-2024-40972

CVSS v2.0

7.5

High

VectorAV:N/AC:L/Au:N/C:P/I:P/A:P
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to the ext4 file system in the Linux kernel. The function ext4 xattr set entry() creates new EA inodes while holding a buffer lock on the external xattr block. This can lead to a deadlock when the file system is corrupted and the quota file is set up to contain an xattr block as a data block. The allocation of EA inodes has been moved out of ext4 xattr set entry() to prevent this issue.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
