CVSS v3.1
7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.10.6
Description
The issue is caused by an integer overflow in the
vmw surface define ioctl function. This can be exploited by a local attacker to cause a denial of service, such as a system hang or crash, or possibly gain privileges, by making a crafted ioctl call for a /dev/dri/renderD* device. The exploitation allows for out-of-bounds write, which can lead to system instability or privilege escalation.Recommendations
For Linux kernel versions prior to 4.10.6, update to version 4.10.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the
/dev/dri/renderD* device to minimize the risk of exploitation.Fix
DoS
Memory Corruption
