CVE-2025-38087

net/sched: fix use-after-free in taprio_dev_notifier

7.8 HighFix available

In the Linux kernel, the following vulnerability has been resolved:

net/sched: fix use-after-free in taprio_dev_notifier

Since taprio’s taprio_dev_notifier() isn’t protected by an RCU read-side critical section, a race with advance_sched() can lead to a use-after-free.

Adding rcu_read_lock() inside taprio_dev_notifier() prevents this.

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

gtp: Destroy device along with udp socket's netns dismantle.

gtp_newlink() links the device to a list in dev_net(dev) instead of src_net, where a udp tunnel socket is created.

Even when src_net is removed, the device stays alive on dev_net(dev). Then, removing src_net triggers the splat below. [0]

In this example, gtp0 is created in ns2, and the udp socket is created in ns1.

ip netns add ns1 ip netns add ns2 ip -n ns1 link add netns ns2 name gtp0 type gtp role sgsn ip netns del ns1

Let's link the device to the socket's netns instead.

Now, gtp_net_exit_batch_rtnl() needs another netdev iteration to remove all gtp devices in the netns.

Since taprio’s taprio_dev_notifier() isn’t protected by an RCU read-side critical section, a race with advance_sched() can lead to a use-after-free.
