CVE-2026-31693
Description
In the Linux kernel, the following vulnerability has been resolved:
cifs: some missing initializations on replay
In several places in the code, we have a label to signify the start of the code where a request can be replayed if necessary. However, some of these places were missing the necessary reinitializations of certain local variables before replay.
This change makes sure that these variables get initialized after the label.
