CVE-2026-80767 — HID: sensor: custom: Fix use-after-free in enable_sensor
In the Linux kernel, the following vulnerability has been resolved: HID: sensor: custom: Fix use-after-free in enable_sensor enable_sensor_store() can call set_power_report_state(), which dereferences sensor_inst->power_state and sensor_inst->report_state. These pointers refer to entries in sensor_inst->fields. Create the field attributes before exposing the enable_sensor sysfs attribute, so enable_sensor cannot be accessed before the state it depends on has been initialized. On remove, delete enable_sensor before freeing the field attributes, so a concurrent sysfs write cannot dereference freed memory through power_state or report_state.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.2% (30-day exploitation probability)+1
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Linux Linux).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?
CVE-2026-80767 is "HID: sensor: custom: Fix use-after-free in enable_sensor", rated Unknown. It affects Linux (Linux); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. EPSS 0.20% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
