CVE-2026-23006: ASoC: tlv320adcx140: fix null pointer

Noroxi assessment

Priority: Monitor (action score 22/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 53bd838ed5950cb18927e4b2e8ee841b7cb10929, 61757f5191daab863d25f03680e912b5449a1eed, 659939d08e5f7bc17b941c53e8c9c0a6c6113b21.

Low priority for now. Upgrade to Linux Linux 53bd838ed5950cb18927e4b2e8ee841b7cb10929, 61757f5191daab863d25f03680e912b5449a1eed, 659939d08e5f7bc17b941c53e8c9c0a6c6113b21 or later.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
