CVE-2025-38336: ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330

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: 0.19% (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 0d9a48dfa934f43ac839211ae4aeba34f666a9a5, 2.6.28, 2.6.29; azl3 kernel 6.6.92.2-2 on Azure Linux 3.0 6.6.96.1-1.

Low priority for now. Upgrade to Linux Linux 0d9a48dfa934f43ac839211ae4aeba34f666a9a5, 2.6.28, 2.6.29; azl3 kernel 6.6.92.2-2 on Azure Linux 3.0 6.6.96.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330 The controller has a hardware bug that can hard hang the system when doing ATAPI DMAs without any trace of what happened. Depending on the device attached, it can also prevent the system from booting. In this case, the system hangs when reading the ATIP from optical media with cdrecord -vvv -atip on an _NEC DVD_RW ND-4571A 1-01 and an Optiarc DVD RW AD-7200A 1.06 attached to an ASRock 990FX Extreme 4, running at UDMA/33. The issue can be reproduced by running the same command with a cygwin build of cdrecord on WinXP, although it requires more attempts to cause it. The hang in that case is also resolved by forcing PIO. It doesn't appear that VIA has produced any drivers for that OS, thus no known workaround exists. HDDs attached to the controller do not suffer from any DMA issues.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

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.
