CVE-2026-89729: HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.35% (FIRST EPSS).
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 1c0463f0f028801a933f090cd2695f132635b374, 4145aa149a32e4b35d5d47e380d0c6c438b4e6fe, 8bf8aaf2f74de64f801eb30bc38927dba1f8e40a; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 6.6.157.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1c0463f0f028801a933f090cd2695f132635b374, 4145aa149a32e4b35d5d47e380d0c6c438b4e6fe, 8bf8aaf2f74de64f801eb30bc38927dba1f8e40a; azl3 kernel 6.6.152.1-1 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: HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature sensor_hub_get_feature() clamps its return value to the caller's buffer size, but the copy loop still copies field->report_size / 8 bytes for each report value. A malicious HID descriptor can advertise a large feature field size while an IIO caller supplies a small stack buffer, such as a single s32, causing an out-of-bounds write. HID core stores parsed report values in __s32 slots and clamps extracted values to 32 bits. Reject feature fields that require more than one slot per value, guard the total byte count calculation, and clamp each per-value copy to the remaining caller buffer.

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.
