CVE-2022-48942: hwmon: Handle failure to register sensor with thermal zone correctly

Noroxi assessment

Priority: Monitor (action score 22/100)

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: 0.21% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Linux Linux 1b5f517cca36292076d9e38fa6e33a257703e62e, 7efe8499cb90651c540753f4269d2d43ede14223, 8a1969e14ad93663f9a3ed02ccc2138da9956a0e.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1b5f517cca36292076d9e38fa6e33a257703e62e, 7efe8499cb90651c540753f4269d2d43ede14223, 8a1969e14ad93663f9a3ed02ccc2138da9956a0e or later.

In the Linux kernel, the following vulnerability has been resolved: hwmon: Handle failure to register sensor with thermal zone correctly If an attempt is made to a sensor with a thermal zone and it fails, the call to devm_thermal_zone_of_sensor_register() may return -ENODEV. This may result in crashes similar to the following. Unable to handle kernel NULL pointer dereference at virtual address 00000000000003cd ...

If the call fails with -ENODEV, report that the sensor was not attached to a thermal zone but continue to register the hwmon device.

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.

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.

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.
