CVE-2026-72479: iio: accel: mma8452: handle I2C read error(s) in mma8452_read()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 1cddef80a180af74c33d2f26c962ce92b60fded4, 5bdff291d20c31b365d9ddfe9c426fbfb41da5bb, b488055e81d9faaaf2f8aaff45f9944040ac4493.

Low priority for now. Upgrade to Linux Linux 1cddef80a180af74c33d2f26c962ce92b60fded4, 5bdff291d20c31b365d9ddfe9c426fbfb41da5bb, b488055e81d9faaaf2f8aaff45f9944040ac4493 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: iio: accel: mma8452: handle I2C read error(s) in mma8452_read() Currently, If i2c_smbus_read_i2c_block_data() fails but mma8452_set_runtime_pm_state() succeeds, mma8452_read() returns 0. As a result, the caller mma8452_read_raw() assumes the read was successful and proceeds to use a buffer containing uninitialized stack memory. Add proper checking of the I2C read return value and propagate errors to the caller.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

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.
