Descriptions

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

spi: hisi-sfc-v3xx: Return IRQ_NONE if no interrupts were detected

Return IRQ_NONE from the interrupt handler when no interrupt was
detected. Because an empty interrupt will cause a null pointer error:

Unable to handle kernel NULL pointer dereference at virtual
address 0000000000000008
Call trace:
complete+0x54/0x100
hisi_sfc_v3xx_isr+0x2c/0x40 [spi_hisi_sfc_v3xx]
__handle_irq_event_percpu+0x64/0x1e0
handle_irq_event+0x7c/0x1cc

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
