CVE-2026-46091 Details
Description
In the Linux kernel, the following vulnerability has been resolved: media: rc: igorplugusb: heed coherency rules In a control request, the USB request structure can be subject to DMA on some HCs. Hence it must obey the rules for DMA coherency. Allocate it separately.
A vulnerability in the Linux kernel's handling of USB control requests for the IgorPlug-USB device can lead to issues with Direct Memory Access (DMA) coherency. This vulnerability affects the stable versions of the Linux kernel. The problem arises because the USB request structure can be subjected to DMA on certain host controllers, requiring it to adhere to DMA coherency rules. The vulnerability has been addressed by modifying the allocation of the USB control request structure to ensure proper coherency.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the latest kernel version can be found on the official Linux kernel website.
