# CVE-2026-53157

> 3.1 LOW

## Beschreibung

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

net: phonet: free phonet_device after RCU grace period

phonet_device_destroy() removes a phonet_device from the per-net device
list with list_del_rcu(), but frees it immediately. RCU readers walking
the same list can still hold a pointer to the object after it has been
removed, leading to a slab-use-after-free.

Use kfree_rcu(), matching the lifetime rule already used by
phonet_address_del() for the same object type.
