In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix double-free in SMB2_open() replay
A response-bearing attempt can return a replayable error and free its response buffer. If SMB2_open_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.
Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
