Detailsinfo

A vulnerability was found in Linux Kernel up to 6.6.142/6.12.92/6.18.34/7.0.11. It has been declared as very critical. Affected by this vulnerability is the function usb_fill_control_urb of the file drivers/media/rc/igorplugusb.c of the component igorplugusb. The manipulation of the argument request with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: media: rc: igorplugusb: fix control request setup packet Commit eac69475b01f ("media: rc: igorplugusb: heed coherency rules") changed the control request storage from an embedded struct to an allocated pointer so it can obey DMA coherency rules. However, the driver still passes &ir->request to usb_fill_control_urb(). That points the URB setup packet at the pointer field itself rather than at the allocated struct usb_ctrlrequest. USB core then interprets pointer bytes as the setup packet. This can produce an invalid bRequestType and trigger the control direction warning reported by syzbot: usb 2-1: BOGUS control dir, pipe 80003580 doesn't match bRequestType 0 Pass ir->request itself as the setup packet.

It is possible to read the advisory at git.kernel.org. This vulnerability is known as CVE-2026-64240 since 07/19/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 07/24/2026).

Upgrading to version 6.6.143, 6.12.93, 6.18.35 or 7.0.12 eliminates this vulnerability. Applying the patch e823e4294511989f5962e7ad85bf4d179ba74f52/2243ad78ce64d344754260533ae7730c2174a34a/aa22590a16e51455c6db802c774b31aadc604a9a/060fca8e098387f949e4eedaf215d952e477ac12/0d880d2db9856e94127ab09331363bef59f98005/f33b5a61673bd220fdaaf4202cf1013d6d66c943/5cc3f6db72f77d1a8f7f1cf4ac01803927ffdf15/171022c7d594c133a45f92357a2a91475edabe20 is able to eliminate this problem.
