CVE-2026-43215 cifs: Fix locking usage for tcon fields

In the Linux kernel, the following vulnerability has been resolved: cifs: Fix locking usage for tcon fields We used to use the cifstcpseslock to protect a lot of objects that are not just the server, ses or tcon lists. We later introduced srvlock, seslock and tclock to protect fields within the...

CVE-2026-43215

The CVE-2026-43215 issue affects the Linux kernel CIFS implementation: the code used cifs_tcp_ses_lock to guard tcon fields, but this lock protected more than intended. The patch introduces more granular locking (tc_lock) within tcon-related structures (in addition to srv_lock and ses_lock) to re...
