CVE-2026-64384
Description
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix change notify replay double-free
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_notify_init() fails before the next send, cleanup
retains the previous buffer type and frees that response again.
Reset response bookkeeping before each attempt to prevent the stale free.
