Description
In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - only expose sysfs attributes on control interface
When the driver was converted to use the driver core to instantiate device attributes (via .dev_groups in the usb_driver structure), the attributes started appearing on all interfaces bound to the driver. Since the ims-pcu driver manually claims the secondary data interface during probe, the driver core automatically creates the sysfs attributes for that interface as well.
However, the driver only supports these attributes on the primary control interface. Data interfaces lack the necessary descriptors and internal state to handle these requests, and accessing them can lead to unexpected behavior or crashes.
Fix this by updating the is_visible() callbacks for both the main and OFN attribute groups to verify that the interface being accessed is indeed the control interface.
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-2026-80596 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-2026-80596 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-2026-80596. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
