Name of the Vulnerable Software and Affected Versions
Linux kernel versions 4.9.x through 4.10.3
Description
The issue is caused by a buffer overflow in the
drivers/media/usb/dvb-usb/dw2102.c driver of the Linux kernel. It can be exploited by a local attacker who interacts incorrectly with the CONFIG VMAP STACK parameter, potentially causing a denial of service, such as a system crash or memory corruption. The exploitation may also have other unspecified impacts by using more than one virtual page for a DMA scatterlist.Recommendations
For Linux kernel versions 4.9.x through 4.10.3, update to version 4.10.4 or later to resolve the issue.
As a temporary workaround, consider restricting interactions with the
CONFIG VMAP STACK option to minimize the risk of exploitation.Correção
