CVE-2022-50107:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2022-50107 affects the Linux kernel and was disclosed on June 18, 2025. The vulnerability is related to a memory leak in the CIFS (Common Internet File System) filesystem implementation when using fscache functionality (NVD, Wiz).
Technical details
The vulnerability occurs when the 'index == next_cached' case is hit, resulting in a leaked reference count on the struct page. This issue specifically affects the CIFS filesystem module when used in conjunction with fscache. The fix involves using readahead_folio() which properly handles the reference counting (NVD, Wiz).
Impact
The vulnerability leads to memory leaks in the Linux kernel, which could potentially result in system resource exhaustion over time if repeatedly triggered (Wiz).
Mitigation and workarounds
The issue has been fixed by using readahead_folio() which properly handles the reference counting. Users should update to a patched version of the Linux kernel that includes this fix (Wiz).
