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 the Linux kernel. Users should update to the fixed kernel versions identified by the commits (hashes provided) to remediate this issue.

Description

A vulnerability in the Linux kernel's drm/imagination driver caused incorrect propagation of map failures from the pvr_mmu_map_sgl() function. This flaw led the pvr_mmu_map() interface to continue operation instead of returning an error, potentially causing a kernel NULL pointer dereference and system crash. The issue has been fixed by ensuring proper error codes are returned from pvr_mmu_map_sgl().

Impact

The vulnerability can cause a kernel NULL pointer dereference resulting in an internal error and system crash (kernel panic). This impacts system stability and availability but does not indicate privilege escalation or data corruption directly.

Summary

The Linux kernel's drm/imagination component had a flaw where map failures from the pvr_mmu_map_sgl() interface were not correctly propagated to the pvr_mmu_map() interface. As a result, pvr_mmu_map() continued execution despite errors, leading to a NULL pointer dereference and kernel crash. The fix involves returning the correct error code from pvr_mmu_map_sgl() to prevent further erroneous processing. The vulnerability was identified with a detailed kernel crash call stack and has been resolved in specific commits.
