CVE-2026-43316: media: solo6x10: Check for out of bounds chip_id

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (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 0b3dadada2417782a63ce32dae05bafe1c949e3f, 0fdf6323c35a134f206dcad5babb4ff488552076, 33af366211ee78e3b074ff44a16121e537e86826.

Low priority for now. Upgrade to Linux Linux 0b3dadada2417782a63ce32dae05bafe1c949e3f, 0fdf6323c35a134f206dcad5babb4ff488552076, 33af366211ee78e3b074ff44a16121e537e86826 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: media: solo6x10: Check for out of bounds chip_id Clang with CONFIG_UBSAN_SHIFT=y noticed a condition where a signed type (literal "1" is an "int") could end up being shifted beyond 32 bits, so instrumentation was added (and due to the double is_tw286x() call seen via inlining), Clang decides the second one must now be undefined behavior and elides the rest of the function[1]. This is a known problem with Clang (that is still being worked on), but we can avoid the entire problem by actually checking the existing max chip ID, and now there is no runtime instrumentation added at all since everything is known to be within bounds. Additionally use an unsigned value for the shift to remove the instrumentation even without the explicit bounds checking. [hverkuil: fix checkpatch warning for is_tw286x]

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

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.
