- Summary
- smb: client: fix double-free in SMB2_ioctl() replay
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix double-free in SMB2_ioctl() replay
A response-bearing attempt can return a replayable error and free its response buffer. If SMB2ioctlinit() 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.
