Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-93165)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 1.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local privileged user to overread memory.

The vulnerability exists due to an out-of-bounds read in cros_ec_sensorhub_ring_handler() when processing FIFO information responses from EC firmware. A local privileged user can cause the handler to process a response whose length is shorter than expected to overread memory.

The condition can occur when EC firmware reports inconsistent maximum response and sensor-count values.
