CVE-2026-98566: drm/imagination: clamp freelist reconstruction requests

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 45585c3aa285854face65293acc95eff73063d6d, b78f8f5532a077baa4aabccf657a4fb3b164659e, e0560db0ea6e10c283ebe7c259a7af8d3b6e61a6.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 45585c3aa285854face65293acc95eff73063d6d, b78f8f5532a077baa4aabccf657a4fb3b164659e, e0560db0ea6e10c283ebe7c259a7af8d3b6e61a6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: clamp freelist reconstruction requests The firmware reconstruction count controls accesses to the request's fixed freelist ID array and the copy into the fixed response array. Neither access currently bounds the count to those protocol arrays. Clamp the count to the request capacity, which is shared by the response layout, and use that count consistently for reconstruction and response publication. Keep the firmware recovery exchange instead of dropping an oversized request without a response, as discussed with the firmware maintainer. The issue was found by our static-analysis tool.
