CVE-2026-64530

CVE-2026-64530 affects the Linux kernel net/sched subsystem. The root cause is that tcf_qevent_handle() did not properly handle TC_ACT_CONSUMED, causing the skb to be returned to the caller as if classification passed, while the defragmentation engine still owned it. This led to a use-after-free ...

The vulnerability of the ets_qdisc_change() function in the net/sched/sch_ets.c module of the network/sched/sch_ets.c subsystem of the Linux operating system’s networking subsystem allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the etsqdiscchange function in the net/sched/schets.c file, within the net/sched subsystem of the Linux kernel’s network management mechanism, relates to operations involving resources after their expiration. Exploiting this vulnerability could allow an attacker to compromise...
