CVE-2024-53080

Local kernel compromise via racy VM lookup

Published Nov 19, 2024 · Updated Aug 5, 2026

Use-after-free in the Linux kernel Panthor DRM driver 6.10 through 6.11.7 allows local users to corrupt kernel memory via ioctls. panthor_vm_pool_get_vm loads a VM pointer from an XArray without its internal lock, then increments a reference after VM_DESTROY can free the object. Render-node access lets a local user race destroy and state, bind, heap, or group ioctls to disclose or corrupt kernel memory or panic the host.
