The vulnerability of the generic_ops_supported() function in the EFI (Extensible Firmware Interface) driver of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the genericopssupported function in the drivers/firmware/efi/efi.c module of the EFI driver for the Linux operating system is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...
