Description

In the Linux kernel, the following vulnerability has been resolved: smb: Initialize cfid->tcon before performing network ops Avoid leaking a tcon ref when a lease break races with opening the cached directory. Processing the leak break might take a reference to the tcon in cached_dir_lease_break() and then fail to release the ref in cached_dir_offload_close, since cfid->tcon is still NULL.

Affected configurations

• linux linux kernel (>= 6.1 < 6.6.64) • linux linux kernel (>= 6.7 < 6.11.11) • linux linux kernel (>= 6.12 < 6.12.2)
