- Summary
- CVE-2026-53157 affecting package kernel for versions less than 6.6.144.1-1
- Details
-
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.
