Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An out-of-bounds read exists in the
nexio read data() function. The function retrieves data len and x len from a packed header in the device interrupt packet and iterates through the packet->data buffer based on these values. Because these 16-bit fields can reach 65535 while the URB transfer buffer is only 1024 bytes, a device providing fraudulent length values can trigger a read of approximately 64 KiB past the coherent DMA allocation. This allows adjacent kernel memory contents to leak to userspace as ABS X / ABS Y events or cause a system fault if an unmapped page is accessed.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
