27 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: um: vector: Do not use drvdata in release The drvdata is not available in release. Let's just use container_of() to get the vector_device instance. Otherwise, removing a vector device will result in a crash: RIP: 0033:vector_device_release+0xf/0x50 RSP: 00000000e187bc40 EFLAGS: 00010202 RAX: 0000000060028f61 RBX: 00000000600f1baf RCX: 00000000620074e0 RDX: 000000006220b9c0 RSI: 0000000060551c80 RDI: 0000000000000000 RBP: 00000000e187bc5... • https://git.kernel.org/stable/c/8ed7793f6f589b4e1f0b38f8448578d2a48f9c82 •

This only ensures that `cp` will not be freed. Therefore, the reference count for `cp` can drop to zero, which will trigger a refcount use-after-free warning when `cache_get` is called.
