CVE-2024-26747

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: roles: soluciona el problema del puntero NULL al colocar la referencia del módulo. En el diseño actual, el controlador de clase de rol usb obtendrá la referencia del módulo principal usb_role_switch después de que el usuario obtenga el dispositivo usb_role_switch y coloque la referencia después del El usuario puso el dispositivo usb_role_switch. Sin embargo, el dispositivo principal de usb_role_switch se puede eliminar antes de que el usuario coloque usb_role_switch. Si es así, entonces, el problema del puntero NULL se solucionará cuando el usuario coloque la referencia del módulo principal. Esto guardará el puntero del módulo en la estructura de usb_role_switch. Entonces, no necesitamos encontrar el módulo iterando relaciones largas.

In the Linux kernel, the following vulnerability has been resolved: usb: roles: fix NULL pointer issue when put module's reference In current design, usb role class driver will get usb_role_switch parent's module reference after the user get usb_role_switch device and put the reference after the user put the usb_role_switch device. However, the parent device of usb_role_switch may be removed before the user put the usb_role_switch. If so, then, NULL pointer issue will be met when the user put the parent module's reference. This will save the module pointer in structure of usb_role_switch. Then, we don't need to find module by iterating long relations.

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service. It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.
