| Vector | AV:L/AC:L/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a race condition between fcntl and close operations in the Linux kernel, specifically in the filelock subsystem. This could potentially allow an attacker to impact the confidentiality, integrity, and availability of protected information. The problem arises from the reuse of previously freed memory due to concurrent access to a resource, leading to a race condition. The fix involves applying the same solution to the compatibility path for 32-bit kernels as was applied to the normal version.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
