CVE-2026-80728: Revert "drm/amdgpu: fix aperture mapping leak"

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: 0.16% (FIRST EPSS).
  • Fixed version: Linux Linux 496846a9411136eb9e86ad4f4e62d751bd1e1db5, 6.12.104, 6.18.45; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 Release Notes; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.157.1-1.

Low priority for now. Upgrade to Linux Linux 496846a9411136eb9e86ad4f4e62d751bd1e1db5, 6.12.104, 6.18.45; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 Release Notes; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.157.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: Revert "drm/amdgpu: fix aperture mapping leak" devres teardown is LIFO. The aperture devres node was registered after the DRM device node, so devres_release_all() unmaps the aperture before the DRM device release callback fires amdgpu_device_fini_sw(). IP sw_fini callbacks (e.g. vcn_v4_0_sw_fini) write to fw_shared through a pointer derived from aper_base_kaddr, causing a kernel page fault on probe failure / rollback: BUG: unable to handle page fault ... PMD 0 RIP: vcn_v4_0_sw_fini+0x7b/0x170 [amdgpu] Call Trace: amdgpu_device_fini_sw amdgpu_driver_release_kms devm_drm_dev_init_release devres_release_all This reverts commit d871e99879cb5fd1fa798b006b4888887e63a17a. (cherry picked from commit 336e0cd576817ac64a4b394ca2b3680029f3e37f)

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Technical details

No CVSS vector for this record, so attack conditions can't be derived.

Weakness class (CWE)

Attack context

MITRE CAPEC attack patterns and ATT&CK techniques for this weakness class (CWE). A starting point for detection rules and threat hunting.
