Description
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: fix firmware control interface bounds checks
panthor_init_cs_iface() and panthor_init_csg_iface() validate firmware control interface offsets with 32-bit arithmetic and the size of the host wrapper structures. The offsets are derived from firmware-provided strides, so the arithmetic can wrap before the bounds check, and the host wrapper size is not the size of the firmware control interface being mapped.
Use 64-bit arithmetic for the computed offsets and validate against the actual firmware control interface structure sizes with subtraction-based bounds checks. Also validate that the shared section is large enough for the global control interface before using it.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-89825 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-89825 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-89825. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
