CVE-2024-36973

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: misc: microchip: pci1xxxx: corrige double free en el manejo de errores de gp_aux_bus_probe() Cuando auxiliar_device_add() devuelve error y luego llama a auxiliar_device_uninit(), la función de devolución de llamada gp_auxiliary_device_release() llama a ida_free( ) y kfree(aux_device_wrapper) para liberar memoria. No deberíamos volver a llamarlos en la ruta de manejo de errores. Solucione este problema omitiendo las funciones de limpieza redundantes.

In the Linux kernel, the following vulnerability has been resolved: misc: microchip: pci1xxxx: fix double free in the error handling of gp_aux_bus_probe() When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), callback function gp_auxiliary_device_release() calls ida_free() and kfree(aux_device_wrapper) to free memory. We should't call them again in the error handling path. Fix this by skipping the redundant cleanup functions.

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service.
