- Summary
- smb/server: fix potential null-ptr-deref of lease_ctx_info in smb2_open()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
smb/server: fix potential null-ptr-deref of leasectxinfo in smb2_open()
null-ptr-deref will occur when (reqoplevel == SMB2OPLOCKLEVELLEASE) and parselease_state() return NULL.
Fix this by check if 'leasectxinfo' is NULL.
Additionally, remove the redundant parentheses in parsedurablehandle_context().
