CVE-2023-28410
Description
A flaw has been identified in the Linux kernel i915 graphics driver that improperly restricts operations within the bounds of a memory buffer. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.
Statement
This has been rated as having a Moderate security impact until more information is available, such as exploit or description. The potential corruption of memory is expected to have impact on availability, leading to a system crash.
Mitigation
Preventing loading the i915 kernel module will prevent attackers from using this exploit against the system; however, the power management functionality of the card will be disabled and the system may draw additional power. See the kcs “How do I blacklist a kernel module to prevent it from loading automatically?“ (https://access.redhat.com/solutions/41278) for instructions on how to disable a kernel module from autoloading. Graphical displays may also be at low resolution or not work correctly.
This mitigation may not be suitable if the graphical login functionality is required.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
