- Summary
- smb: Initialize cfid->tcon before performing network ops
- Details
-
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 cacheddirleasebreak() and then fail to release the ref in cacheddiroffloadclose, since cfid->tcon is still NULL.
