Description

relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local users to cause a denial of service (such as relay blockage) by triggering a NULL alloc_percpu result. A NULL pointer dereference flaw may occur in the Linux kernel’s relay_open in kernel/relay.c. if the alloc_percpu() function is not validated in time of failure and used as a valid address for access. An attacker could use this flaw to cause a denial of service.
