In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix null pointer dereference in svc_rqst_free() When alloc_pages_node() returns null in svc_rqst_alloc(), the null rq_scratch_page pointer will be dereferenced when calling put_page() in svc_rqst_free(). Fix it by adding a null check. Addresses-Coverity: ("Dereference after null check")
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: SUNRPC: corrige la desreferencia del puntero nulo en svc_rqst_free() Cuando alloc_pages_node() devuelve nulo en svc_rqst_alloc(), el puntero nulo rq_scratch_page será desreferenciado al llamar a put_page() en svc_rqst_free(). Solucionarlo agregando una marca nula. Direcciones-Cobertura: ("Desreferencia después de verificación nula")
