Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential cfid UAF in
 smb2_query_info_compound When smb2_query_info_compound() retries, a previously allocated cfid may have
 been freed in the first attempt. Because cfid wasn't reset on replay, later cleanup could act on a stale
 pointer, leading to a potential use-after-free. Reinitialize cfid to NULL under the replay label. Example
 trace (trimmed): refcount_t: underflow; use-after-free. WARNING: CPU: 1 PID: 11224 at ../lib/refcount.c:28
