CVE-2026-74295: ASoC: codecs: hdac_hdmi: Validate written enum value
In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: hdachdmi: Validate written enum value
hdachdmisetpinportmux() uses the written enum value to index the texts array before calling sndsocdapmputenumdouble(), which validates that the value is within the enum item range.
An out-of-range value can therefore make the driver read past the texts array before the helper rejects the write. Move the lookup after the helper has accepted the value.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Update the Linux kernel to the version where this vulnerability has been resolved (Move the lookup after the helper so that the texts array is not indexed before the helper rejects out-of-range values).
