Title
ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330
Summary
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.

Depending on the\ndevice attached, it can also prevent the system from booting.\n\nIn this case, the system hangs when reading the ATIP from optical media\nwith cdrecord -vvv -atip on an _NEC DVD_RW ND-4571A 1-01 and an\nOptiarc DVD RW AD-7200A 1.06 attached to an ASRock 990FX Extreme 4,\nrunning at UDMA/33.\n\nThe issue can be reproduced by running the same command with a cygwin\nbuild of cdrecord on WinXP, although it requires more attempts to cause\nit. The hang in that case is also resolved by forcing PIO. It doesn\u0027t\nappear that VIA has produced any drivers for that OS, thus no known\nworkaround exists.\n\nHDDs attached to the controller do not suffer from any DMA issues."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
