CVE-2026-64437
CVE-2026-64437 affects the ksmbd component of the Linux kernel. A use-after-free in a deferred file_lock can be triggered by a sequence of SMB2_CLOSE followed by SMB2_CANCEL, allowing an authenticated SMB client to cause a kernel crash (denial of service) via the freed file_lock. The root cause i...
