  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: phonet: free phonet_device after RCU grace period\n\nphonet_device_destroy() removes a phonet_device from the per-net device\nlist with list_del_rcu(), but frees it immediately. RCU readers walking\nthe same list can still hold a pointer to the object after it has been\nremoved, leading to a slab-use-after-free.\n\nUse kfree_rcu(), matching the lifetime rule already used by\nphonet_address_del() for the same object type.",
