NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by AlmaLinux.

In the Linux kernel, the following vulnerability has been resolved:

net/sched: mqprio: fix stack out-of-bounds write in tc entry parsing

TCA_MQPRIO_TC_ENTRY_INDEX is validated using NLA_POLICY_MAX(NLA_U32, TC_QOPT_MAX_QUEUE), which allows the value TC_QOPT_MAX_QUEUE (16). This leads to a 4-byte out-of-bounds stack write in the fp[] array, which only has room for 16 elements (0–15).

Fix this by changing the policy to allow only up to TC_QOPT_MAX_QUEUE - 1.
