Descriptions
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_core: Fix possible buffer overflow
struct hci_dev_info has a fixed size name[8] field so in the event that
hdev->name is bigger than that strcpy would attempt to write past its
size, so this fixes this problem by switching to use strscpy.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Bluetooth: hci_core: soluciona un posible desbordamiento del búfer struct hci_dev_info tiene un campo de nombre de tamaño fijo[8], por lo que en caso de que hdev->name sea mayor que strcpy intentaría escribir más allá su tamaño, por lo que esto soluciona este problema cambiando al uso de strscpy.
A buffer overflow flaw was found in struct hci_dev_info in the variable name[8] in the Linkkux Kernel. If an attacker crafts an exploit copying more than the size of the name[8], it results in a buffer overflow and a denial of service.
