CVE-2024-44957

CVE-2024-44957 is a Linux kernel issue affecting the Xen privcmd path, where irqfds handling could deadlock if mutexes were used under spin_lock_irqsave. The root cause is switching the synchronization primitive for irqfd wakeups from a mutex to a spinlock, due to EPOLLHUP being delivered to irqf...
