Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.9.7
Description
The issue is caused by an integer overflow in the
vc4 get bcl function of the VideoCore DRM driver. This can be exploited by a local attacker using a specially crafted VC4 SUBMIT CL ioctl call with a malicious size value, potentially leading to a denial of service or other unspecified impacts.Recommendations
For Linux kernel versions prior to 4.9.7, update to version 4.9.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the
vc4 get bcl function or the VC4 SUBMIT CL ioctl call to minimize the risk of exploitation.Correção
