NewCVE-2026-89851 (opens in a new tab)How to fix?
Upgrade Debian:12 linux-6.12 to version 6.12.111-1~deb12u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream linux-6.12 package and not the linux-6.12 package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
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.
