Описание
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: fix linked list corruption
Never leave scheduled wcid entries on the temporary on-stack list
A flaw was found in the linux kernal wifi subsystem mt76_txq_schedule_pending_wcid() and mt76_txq_schedule_pending() functions of the mt76 driver. Under certain conditions, scheduled wcid entries are left on a temporary on‑stack list, which may lead to linked‑list corruption and memory corruption, allowing a local attacker to cause a denial of service.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
