AI-suggested
A patch is available and should be applied by upgrading to Linux kernel versions 7.0.0-27.27 or later. The vendor advisory confirms the issue is fixed in these versions. No additional mitigation is required beyond applying the official fix.
Description
A vulnerability in the Linux kernel's Qualcomm LPG LED driver (qcom-lpg) was identified where an array overflow could occur when selecting high resolution values. The issue arises because FIELD_GET() extracts a 3-bit value used to index an array of only 5 elements, potentially causing out-of-bounds access. This flaw has been fixed in Linux kernel versions 7.0.0-27.27 and later. The vulnerability has a CVSS score of 5.5 with a low severity rating and does not impact confidentiality or integrity but affects availability. No known exploits are reported in the wild. The vendor has released patches addressing this issue.
