CVE-2025-68814

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

Description A memory leak exists in the io openat prep() function due to improper cleanup of a struct filename when a file is installed in the fixed file table with the O CLOEXEC flag set. The function allocates memory for the struct filename using getname(), but this memory is not released if the function returns early, leading to a memory leak. The issue occurs because the REQ F NEED CLEANUP flag is not set for the request after a successful getname() call.

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