A fix is available — apply it.

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

ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping

When an invalid value is passed via quirk option, currently bytcr_rt5640 driver only shows an error message but leaves as is. This may lead to unepxected results like OOB access.

This patch corrects the input mapping to the certain default value if an invalid value is passed.

Data Freshness Timeline

(refreshed 11× in last 7d / 36× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 95 of 207 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 5 repeat rows among the latest 100 are merged into the row they repeat. The 112 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
