CVE-2022-49616

Status: AnalyzedMedium (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

ASoC: rt7*-sdw: harden jack_detect_handler

Realtek headset codec drivers typically check if the card is instantiated before proceeding with the jack detection.

The rt700, rt711 and rt711-sdca are however missing a check on the card pointer, which can lead to NULL dereferences encountered in driver bind/unbind tests.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
