CVE-2022-50356

CVE-2022-50356 affects the Linux kernel’s net: sched: sfb path. When the default qdisc is sfb and dev_queue initialization fails during mqprio_init(), the code calls sfb_reset() to free resources, but the qdisc pointer (q->qdisc) may be NULL, leading to a general protection fault (null pointer...
