A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A fix is available and has been applied in multiple Linux kernel commits identified by hashes (e36284257eeca13768687bf8e52f66f8ea0e8794, dc64cf9d71428234389b635d142cb5fe07d57eab, d4bee74b7cb93e40c60b43dc9dc0c3aab444649f, b303e1d52811de7d1bcf793560754d4df68d4a1c, 2f021d93f15829ba052ff22bc40df0ec3ae7c7ab). Users should update to a kernel version including these fixes. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's drm/msm driver involves improper handling of hung GPU submits during recovery. Retiring a hung submit before the GPU recovery completes can cause GPU page faults due to premature buffer object (BO) freeing. The issue is fixed by deferring the retirement of submits until after GPU recovery is complete.

Impact

If exploited, this vulnerability could cause GPU page faults and potential instability or crashes in systems using the affected drm/msm driver. This could affect graphics processing reliability but no direct code execution or privilege escalation impact is described.

Summary

CVE-2026-100077 addresses a flaw in the Linux kernel drm/msm driver where retiring a hung submit before the GPU has recovered can lead to GPU page faults. This occurs because retiring the submit triggers buffer object freeing while the GPU may still be accessing those objects. The fix involves changing the recovery logic to retire submits only after the GPU recovery process finishes, preventing premature BO free and associated faults.
