Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 5.3.13
Description:
The issue is related to an integer overflow in the
cpia2 remap buffer function, located in drivers/media/usb/cpia2/cpia2 core.c, which can be exploited to gain read and write access to kernel physical pages. This could potentially result in privilege escalation. The vulnerability can be exploited by local users with access to /dev/video0.Recommendations:
For Linux kernel versions prior to 5.3.13, update to a version that contains a fix for this issue to prevent potential privilege escalation.
As a temporary workaround, consider restricting access to
/dev/video0 to minimize the risk of exploitation.Exploit
