CVE-2026-53011 net/sched: taprio: fix use-after-free in advance_sched() on schedule switch

In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: fix use-after-free in advancesched on schedule switch In advancesched, when shouldchangeschedules returns true, switchschedules is called to promote the admin schedule to oper. switchschedules queues the old op...

CVE-2026-53011

The CVE-2026-53011 issue affects the Linux kernel net/sched taprio code. In advance_sched(), when should_change_schedules() is true, switch_schedules() promotes the admin schedule to oper and queues the old oper for RCU freeing, but next may still point into the old oper. The subsequent end_time ...

CVE-2026-52994

The CVE-2026-52994 vulnerability affects the Linux kernel’s vsock/virtio code, where the MSG_ZEROCOPY pinned-pages accounting could bypass RLIMIT_MEMLOCK on the last skb due to iter->count being consumed earlier. The fix makes pkt_len (the total bytes sent) the parameter to virtio_transport_in...
