CVE-2024-46762

CVE-2024-46762 affects the Linux kernel xen privcmd path. A race between privcmd_irqfd_assign() and privcmd_irqfd_deassign() can leave a previously freed kirqfd in use, allowing access to a freed kirqfd and causing a kernel oops. The issue is mitigated by applying SRCU locking to irqfds, mirrorin...
