Summary
CVE-2025-38568 affecting package kernel for versions less than 6.6.104.2-1
Details

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

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

TCAMQPRIOTCENTRYINDEX is validated using NLAPOLICYMAX(NLAU32, TCQOPTMAXQUEUE), which allows the value TCQOPTMAX_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 TCQOPTMAX_QUEUE - 1.
