CVE-2026-46091: In the Linux kernel, the following vulnerability has been resolved: media: rc: igorplugusb: heed coherency rules In a
Summary
A vulnerability in the Linux kernel's igorplugusb driver (a USB remote control device) allows unsafe memory access because USB request structures weren't following DMA coherency rules (memory access safety requirements when hardware directly accesses system memory). The fix allocates the USB request structure separately to ensure it complies with proper memory coherency standards.
Solution / Mitigation
This vulnerability was resolved in the Linux kernel through commits available at: https://git.kernel.org/stable/c/0adac0ee2c42027d80bac02ea9b576a88f8955d3, https://git.kernel.org/stable/c/0be8fcd9005e3d3b5a61fe34b070a9663adbb4dc, https://git.kernel.org/stable/c/18d6a7c9e4e63c57157e9a57dd9bf3cd38e4c45a, https://git.kernel.org/stable/c/a62ca67e3c72fb297dc7c86495ba8f7329d7f150, and https://git.kernel.org/stable/c/eac69475b01fe1e861dfe3960b57fa95671c132e.
