Upgrade SLES:15.6 kernel-64kb-devel to version 6.4.0-150600.23.17.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-64kb-devel package and not the kernel-64kb-devel package as distributed by SLES.
See How to fix? for SLES:15.6 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
net/sched: taprio: always validate TCA_TAPRIO_ATTR_PRIOMAP
If one TCA_TAPRIO_ATTR_PRIOMAP attribute has been provided, taprio_parse_mqprio_opt() must validate it, or userspace can inject arbitrary data to the kernel, the second time taprio_change() is called.
First call (with valid attributes) sets dev->num_tc to a non zero value.
Second call (with arbitrary mqprio attributes) returns early from taprio_parse_mqprio_opt() and bad things can happen.
