CVE-2026-52997

The CVE-2026-52997 issue affects the Linux kernel’s net/sched sch_dualpi2 qdisc. The root cause was that dualpi2_change() could attempt to dequeue from the C-queue even when it was empty while packets resided in the L-queue, leading to a NULL skb dereference during limit/memlimit enforcement. The...

CVE-2026-52989

CVE-2026-52989 affects the Linux kernel nvmet-tcp component. The root cause is that nvmet_tcp_build_pdu_iovec() detects out-of-bounds PDU length/offset but does not propagate the error to callers; it returns void and triggers nvmet_tcp_fatal_error(cmd->queue) without alerting the caller, leavi...

CVE-2026-52987

In the Linux kernel, CVE-2026-52987 arises from drm/amdgpu: double calls to drm_exec_fini() in userq_validate when new_addition is true. The code calls drm_exec_fini(&exec) before iterating HMM ranges and then, if amdgpu_ttm_tt_get_user_pages() fails, executes a second drm_exec_fini(&exec) on the...

CVE-2026-52984 net/sched: netem: fix queue limit check to include reordered packets

In the Linux kernel, the following vulnerability has been resolved: net/sched: netem: fix queue limit check to include reordered packets The queue limit check in netemenqueue uses q-tlen which only counts packets in the internal tfifo. Packets placed in sch-q by the reorder path qdiscenqueuehead...

CVE-2026-52984

CVE-2026-52984 affects the Linux kernel netem queue limit check in net/sched. The bug counts queue length using q->t_len, excluding packets enqueued via reorder (__qdisc_enqueue_head); fix adds sch->q.qlen to the limit check. Impact is local, with potential high availability impact under pa...

CVE-2026-52976

The CVE-2026-52976 issue affects the Linux kernel drm/xe driver. Two error-handling paths in xe_exec_queue_create_ioctl() can lead to memory corruption: (1) on xe_hw_engine_group_add_exec_queue() failure, the cleanup jumps to cleanup without xe_exec_queue_kill(), potentially leaving a queue in th...
