CVE-2024-53148

In the Linux kernel, the following vulnerability has been resolved: comedi: Flush partial mappings in error case If some remappfnrange calls succeeded before one failed, we still have buffer pages mapped into the userspace page tables when we drop the buffer reference with comedibufmapputbm. The...

CVE-2024-53148

CVE-2024-53148 affects the Linux kernel (comedi subsystem). The issue: if remap_pfn_range() calls partially succeed before a failure, some buffer pages remain mapped in userspace page tables after dropping the buffer reference, and cleanup occurs too late in the mmap error path. The root cause is...

CVE-2021-47364

In the Linux kernel, the following vulnerability has been resolved: comedi: Fix memory leak in compatinsnlist compatinsnlist handles the 32-bit version of the COMEDIINSNLIST ioctl whenwhen CONFIGCOMPAT is enabled. It allocates memory to temporarily hold an array of struct comediinsn converted fro...

CVE-2021-47477 comedi: dt9812: fix DMA buffers on stack

In the Linux kernel, the following vulnerability has been resolved: comedi: dt9812: fix DMA buffers on stack USB transfer buffers are typically mapped for DMA and must not be allocated on the stack or transfers will fail. Allocate proper transfer buffers in the various command helpers and return ...

CVE-2024-26867

CVE-2024-26867 concerns the Linux kernel issue in comedi_8255: subdevice initialization. The root cause, described across multiple sources, is a refactoring in comdrivers/comedi_8255.c where the io field in subdev_8255_private could be left NULL after initialization, because __subdev_8255_init() ...
