VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A use-after-free issue is possible in the Linux kernel due to insufficient checks on file reference counts. This occurs when one thread destroys a file while another thread holds a reference to it. The issue is resolved by taking a lock around the section that removes the file from the file table, preventing two threads from acquiring the same file pointer.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
