Linux: Out-of-bounds Read
CVE-2024-42264 is a high-severity out-of-bounds read vulnerability in Linux, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 73ad583bd4938bf37d2709fc36901eb6f22f2722, 6ce9efd12ae81cf46bf44eb0348594558dfbb9d2 as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.22% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Linux to 73ad583bd4938bf37d2709fc36901eb6f22f2722 or 6ce9efd12ae81cf46bf44eb0348594558dfbb9d2, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.10.4 or a later version.

How the severity score breaks down
- Attack vector
- LocalThe attacker needs local access or must trick a user into running something.
- Attack complexity
- LowNo special conditions are needed; the attack works reliably.
- Privileges required
- LowA basic user account is enough.
- User interaction
- NoneNo action by a victim is required.
- Scope
- UnchangedImpact stays within the vulnerable component.
- Confidentiality

Official description
In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Prevent out of bounds access in performance query extensions Check that the number of perfmons userspace is passing in the copy and reset extensions is not greater than the internal kernel storage where the ids will be copied into. (cherry picked from commit f32b5128d2c440368b5bf3a7a356823e235caabb)

The underlying weakness: Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.
How developers prevent this class of flaw
- Use a language that provides appropriate memory abstractions.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
