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...
