CVE-2019-15505

drivers/media/usb/dvb-usb/technisat-usb2.c en el kernel de Linux hasta la versión 5.2.9 tiene una lectura fuera de los límites a través del tráfico de dispositivos USB diseñado (que puede ser remoto a través de usbip o usbredir).

An out-of-bounds read flaw was found in the DVB USB subsystem of the Linux kernel. There was no boundary check applied to the array in struct technisat_usb2_state state->buf until the 0xff byte is encountered. If the byte is not encountered within the limit, an exposure of kernel data structure occurs. Data confidentiality and system availability are the highest threats with this vulnerability.

It was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not did not handle detach operations correctly, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
