  2. Vulnerabilities (CVE)
  3. CVE-2024-56580
In the Linux kernel, the following vulnerability has been resolved: media: qcom: camss: fix error path on configuration of power domains There is a chance to meet runtime issues during configuration of CAMSS power domains, because on the error path dev_pm_domain_detach() is unexpectedly called with NULL or error pointer. One of the simplest ways to reproduce the problem is to probe CAMSS driver before registration of CAMSS power domains, for instance if a platform CAMCC driver is simply not built.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: qcom: camss: fix error path on configuration of power domains Existe la posibilidad de encontrar problemas de tiempo de ejecución durante la configuración de dominios de energía CAMSS, porque en la ruta de error dev_pm_domain_detach() se llama inesperadamente con NULL o puntero de error. Una de las formas más simples de reproducir el problema es probar el controlador CAMSS antes del registro de dominios de energía CAMSS, por ejemplo, si un controlador CAMCC de plataforma simplemente no está construido. Ejemplo de seguimiento de advertencia: No se puede gestionar la desreferencia del puntero NULL del núcleo en la dirección virtual 00000000000001a2 pc : dev_pm_domain_detach+0x8/0x48 lr : camss_probe+0x374/0x9c0 Seguimiento de llamadas: dev_pm_domain_detach+0x8/0x48 platform_probe+0x70/0xf0 really_probe+0xc4/0x2a8 __driver_probe_device+0x80/0x140 driver_probe_device+0x48/0x170 __device_attach_driver+0xc0/0x148 bus_for_each_drv+0x88/0xf0 __device_attach+0xb0/0x1c0 dispositivo_sonda_inicial+0x1c/0x30 dispositivo_sonda_bus+0xb4/0xc0 función_trabajo_sonda_diferida+0x90/0xd0 trabajo_uno_proceso+0x164/0x3e0 subproceso_trabajador+0x310/0x420 subproceso_k+0x120/0x130 ret_de_bifurcación+0x10/0x20
