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 TCQOPTMAXQUEUE (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 TCQOPTMAXQUEUE - 1.
