Description SMASH SMASH 2023-10-09 13:30:09 UTC 
An array index out-of-bounds write access was found in the Linux kernel in the qfq_update_agg() function, which belongs to the net scheduler QFQ (Quick Fair Queueing Plus). This flaw requires CAP_NET_ADMIN to be exploited and could lead to local privilege escalation.
