CVE-2022-4139: An incorrect TLB flush issue was found in the Linux kernel’s GPU i915 kernel driver, potentially leading to random memory corruption or data
Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.26% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: bpftool (AlmaLinux:8) 4.18.0-425.10.1.el8_7; kernel (AlmaLinux:8) 4.18.0-425.10.1.el8_7; kernel-abi-stablelists (AlmaLinux:8) 4.18.0-425.10.1.el8_7.
- Mentioned 5 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to bpftool (AlmaLinux:8) 4.18.0-425.10.1.el8_7; kernel (AlmaLinux:8) 4.18.0-425.10.1.el8_7; kernel-abi-stablelists (AlmaLinux:8) 4.18.0-425.10.1.el8_7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
An incorrect TLB flush issue was found in the Linux kernel’s GPU i915 kernel driver, potentially leading to random memory corruption or data leaks. This flaw could allow a local user to crash the system or escalate their privileges on the system.
