EUVD-2026-38955

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix leaking freebds While reclaiming the tx queue we fast forward the write pointer to drop any data in flight. These dropped frames are not added back to the pool of free bds. We also need to tell the netdev that ...

CVE-2026-53086

The CVE concerns the Linux kernel bcmgenet driver: the bcmgenet_timeout handler erroneously attempts to bring down all TX queues when a single queue times out, creating race conditions with active queues. The fixed behavior restarts only the timed-out queue, mitigating the race. Reported impact i...

CVE-2026-53087

Summary: CVE-2026-53087 affects the Linux kernel bcmgenet network driver. When reclaiming the transmit queue, the driver advances the write pointer to drop in-flight data but fails to return the dropped frames to the pool of free buffer descriptors (bds), causing a resource leak. This can lead to...

CVE-2026-52997 net/sched: sch_dualpi2: drain both C-queue and L-queue in dualpi2_change()

In the Linux kernel, the following vulnerability has been resolved: net/sched: schdualpi2: drain both C-queue and L-queue in dualpi2change Fix dualpi2change to correctly enforce updated limit and memlimit values after a configuration change of the dualpi2 qdisc. Before this patch, dualpi2change...

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...
