CVE-2024-26776
Estado: AnalizadaMedia (5.5)—
Detalles técnicos trazas, registros y código del informe original
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: spi: hisi-sfc-v3xx: Devuelve IRQ_NONE si no se detectaron interrupciones. Devuelve IRQ_NONE del controlador de interrupciones cuando no se detectó ninguna interrupción. Porque una interrupción vacía causará un error de puntero nulo: No se puede manejar la desreferencia del puntero NULL del kernel en la dirección virtual 0000000000000008 Seguimiento de llamadas: completo+0x54/0x100 hisi_sfc_v3xx_isr+0x2c/0x40 [spi_hisi_sfc_v3xx] __handle_irq_event_percpu+0x64/0x1e0 handle_ evento_irq+0x7c/0x1cc
