Detailsinfo

A vulnerability was found in Linux Kernel up to 6.14.1. It has been classified as problematic. Affected is the function spufs_new_file. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: spufs: fix a leak on spufs_new_file() failure It's called from spufs_fill_dir(), and caller of that will do spufs_rmdir() in case of failure. That does remove everything we'd managed to create, but... the problem dentry is still negative. IOW, it needs to be explicitly dropped.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2025-22073 since 12/29/2024. There are known technical details, but no exploit is available.
