Descriptions

In the Linux kernel, the following vulnerability has been resolved:

RDMA/srpt: Support specifying the srpt_service_guid parameter

Make loading ib_srpt with this parameter set work. The current behavior is
that setting that parameter while loading the ib_srpt kernel module
triggers the following kernel crash:

BUG: kernel NULL pointer dereference, address: 0000000000000000

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/srpt: admite la especificación del parámetro srpt_service_guid. Hace que la carga de ib_srpt con este conjunto de parámetros funcione. El comportamiento actual es que configurar ese parámetro mientras se carga el módulo del kernel ib_srpt desencadena el siguiente fallo del kernel: ERROR: desreferencia del puntero NULL del kernel, dirección: 0000000000000000 Seguimiento de llamadas: parse_one+0x18c/0x1d0 parse_args+0xe1/0x230 load_module+0x8de/ 0xa60 init_module_from_file+0x8b/0xd0 idempotent_init_module+0x181/0x240 __x64_sys_finit_module+0x5a/0xb0 do_syscall_64+0x5f/0xe0 Entry_SYSCALL_64_after_hwframe+0x6e/0x76

A flaw was foundin the Linux Kernel when specifying the srpt_service_guid parameter, which may lead to kernel crash.
