NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-150300_59_109-default package and not the kernel-livepatch-5_3_18-150300_59_109-default package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. This affects qdisc_graft in net/sched/sch_api.c.
