AI-suggested
A patch is available and should be applied. The vendor advisory from Ubuntu (USN-8278-1) confirms that this and other Linux kernel vulnerabilities have been fixed in updated kernel packages. Users should update to the fixed kernel versions to remediate this issue.
Description
A null pointer dereference vulnerability in the Linux kernel's ASoC tlv320adcx140 driver was fixed. The snd_soc_component pointer in the adcx140_priv structure was used without being set, potentially causing a null pointer dereference. This issue was resolved in multiple Linux kernel versions. The vulnerability has a medium severity score and does not impact confidentiality or integrity but can cause availability issues. A patch is available from the vendor.
