Описание

cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).

Описание

hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free that may lead to privilege escalation.
