CVE-2025-38336

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ata: pata_via: Force PIO for ATAPI devices on VT6415/VT6330<br /> <br /> The controller has a hardware bug that can hard hang the system when<br /> doing ATAPI DMAs without any trace of what happened. Depending on the<br /> device attached, it can also prevent the system from booting.<br /> <br /> In this case, the system hangs when reading the ATIP from optical media<br /> with cdrecord -vvv -atip on an _NEC DVD_RW ND-4571A 1-01 and an<br /> Optiarc DVD RW AD-7200A 1.06 attached to an ASRock 990FX Extreme 4,<br /> running at UDMA/33.<br /> <br /> The issue can be reproduced by running the same command with a cygwin<br /> build of cdrecord on WinXP, although it requires more attempts to cause<br /> it. The hang in that case is also resolved by forcing PIO. It doesn&amp;#39;t<br /> appear that VIA has produced any drivers for that OS, thus no known<br /> workaround exists.<br /> <br /> HDDs attached to the controller do not suffer from any DMA issues.
