In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix FCE trace enable parsing in debugfs
qla2x00_dfs_fce_write() called kstrtoul() with a NULL result pointer,
so a successful parse would dereference NULL and oops. Worse, the int
return value (0 on success, negative errno on failure) was assigned to
the unsigned long enable flag, inverting the intended logic: a valid
number was treated as "disable" while a parse failure enabled FCE.
Parse the value into enable and propagate parse errors to userspace.
