UBUNTU-CVE-2025-38349

In the Linux kernel, the following vulnerability has been resolved: eventpoll: don't decrement ep refcount while still holding the ep mutex Jann Horn points out that epoll is decrementing the ep refcount and then doing a mutexunlock&ep-mtx; afterwards. That's very wrong, because it can lead to a...
