CVE-2024-26831

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

Description The issue is related to a memory leak in the Linux kernel's handshake component. The handshake req destroy test1 test started failing after sock release(sock) was replaced with fput(filp) to address the memory leak. The fput(filp) function usually delays the final close and clean-up, which is not consequential in other cases but affects the handshake req destroy test1 test. This test checks that handshake req cancel() followed by closing the file actually calls the ->hp destroy method. The delay in fput(filp) causes the test to fail because it cannot guarantee that the final close is complete before checking the pointer.

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