In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wcd938x: fix missing mbhc init error handling
MBHC initialisation can fail so add the missing error handling to avoid
dereferencing an error pointer when later configuring the jack:
Unable to handle kernel paging request at virtual address fffffffffffffff8

A flaw was found in the Linux kernel's ASoC wcd938x codec component. This vulnerability stems from improper error handling during the initialization of the Multi-Band Headset Controller (MBHC). A local attacker with low privileges could exploit this by triggering a specific sequence of events, leading to an incorrect pointer dereference. This might result in a Denial of Service (DoS), corruption of system memory, or the disclosure of sensitive information.
Отчет
This vulnerability does not affect RHEL 8, nor does it affect releases later than RHEL 9.3.
