Descriptions

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

media: v4l: async: Fix duplicated list deletion

The list deletion call dropped here is already called from the
helper function in the line before. Having a second list_del()
call results in either a warning (with CONFIG_DEBUG_LIST=y):

list_del corruption, c46c8198->next is LIST_POISON1 (00000100)

If CONFIG_DEBUG_LIST is disabled the operation results in a
kernel error due to NULL pointer dereference.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: medios: v4l: async: corregir eliminación de lista duplicada La llamada de eliminación de lista descartada aquí ya se llama desde la función auxiliar en la línea anterior. Tener una segunda llamada a list_del() da como resultado una advertencia (con CONFIG_DEBUG_LIST=y): corrupción de list_del, c46c8198->el siguiente es LIST_POISON1 (00000100). Si CONFIG_DEBUG_LIST está deshabilitado, la operación genera un error del kernel debido a la desreferencia del puntero NULL.
