Exploitation evidence

Disclosed: evidence found.
CVE published 13 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 5 Nov 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

What to do

Upgrade Linux kernel to f8dd66bfb4e184c71bd26418a00546ebe7f5c17a, b963636331fb4f3f598d80492e2fa834757198eb, 338849090ee610ff6d11e5e90857d2c27a4121ab or 6.12.64.

Description

In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Limit num_syncs to prevent oversized allocations The OA open parameters did not validate num_syncs, allowing userspace to pass arbitrarily large values, potentially leading to excessive allocations. Add check to ensure that num_syncs does not exceed DRM_XE_MAX_SYNCS, returning -EINVAL when the limit is violated. v2: use XE_IOCTL_DBG() and drop duplicated check. (Ashutosh) (cherry picked from commit e057b2d2b8d815df3858a87dffafa2af37e5945b)
