Should you act?
Exploited: patch now if you run it
CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Yes, if you run Arm Mali GPU Kernel Driver. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-06-12, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-07-03; treat that as the outer limit, not the target.
- EPSS 0.8%, percentile 55: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 55% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
What it is
Use After Free vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver allows a local non-privileged user to make improper GPU memory processing operations to gain access to already freed memory.This issue affects Bifrost GPU Kernel Driver: from r34p0 through r40p0; Valhall GPU Kernel Driver: from r34p0 through r40p0.
CISA’s summary
Arm Bifrost and Valhall GPU kernel drivers contain a use-after-free vulnerability that allows a local, non-privileged user to make improper GPU memory processing operations to gain access to already freed memory.
