Severity CVSS v4.0:
Pending analysis
Type:
CWE-416 Use After Free
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: phonet: free phonet_device after RCU grace period<br /> <br /> phonet_device_destroy() removes a phonet_device from the per-net device<br /> list with list_del_rcu(), but frees it immediately. RCU readers walking<br /> the same list can still hold a pointer to the object after it has been<br /> removed, leading to a slab-use-after-free.<br /> <br /> Use kfree_rcu(), matching the lifetime rule already used by<br /> phonet_address_del() for the same object type.
