CVE-2025-38336

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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ata: pata_via: Forzar PIO para dispositivos ATAPI en VT6415/VT6330 El controlador tiene un error de hardware que puede bloquear el sistema al realizar DMA ATAPI sin dejar rastro de lo sucedido. Dependiendo del dispositivo conectado, también puede impedir que el sistema arranque. En este caso, el sistema se bloquea al leer el ATIP desde un medio óptico con cdrecord -vvv -atip en un _NEC DVD_RW ND-4571A 1-01 y un Optiarc DVD RW AD-7200A 1.06 conectados a un ASRock 990FX Extreme 4, corriendo en UDMA/33. El problema se puede reproducir ejecutando el mismo comando con una compilación cygwin de cdrecord en WinXP, aunque requiere más intentos para provocarlo. El bloqueo en ese caso también se resuelve forzando PIO. No parece que VIA haya producido ningún controlador para ese sistema operativo, por lo que no existe ninguna solución alternativa conocida. Los discos duros conectados al controlador no sufren ningún problema de DMA.
