Descriptions
In the Linux kernel, the following vulnerability has been resolved:
nfc: fix potential NULL pointer deref in nfc_genl_dump_ses_done
The done() netlink callback nfc_genl_dump_ses_done() should check if
received argument is non-NULL, because its allocation could fail earlier
in dumpit() (nfc_genl_dump_ses()).
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nfc: corrige la posible deref del puntero NULL en nfc_genl_dump_ses_done La devolución de llamada de netlink done() nfc_genl_dump_ses_done() debe verificar si el argumento recibido no es NULL, porque su asignación podría fallar antes en dumpit() (nfc_genl_dump_ses()).
