A malicious device could provide a different endpoint type, which would then be passed to usb_fill_int_urb(), potentially leading to kernel warnings or undefined behavior. Verify that the control endpoint is an interrupt IN endpoint. The Linux kernel CVE team has assigned CVE-2026-72078 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/input/misc/ims-pcu.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/5de5075a1f26166f172b6687cb66810a9b61e3eb https://git.kernel.org/stable/c/7960d99332e03705ec622d92f31e0c77de8baac6 https://git.kernel.org/stable/c/5b96b4da96313dd799a3a40dcfd598d2e2c19217 https://git.kernel.org/stable/c/aa1885f87e60c80e59e50ffd5fb096bf02c83e05 https://git.kernel.org/stable/c/a630508a09b0c05f14bc0843ed409221a93751aa https://git.kernel.org/stable/c/c8d3d83f2eaaf7659de76e8d44e8fc88ee346042 https://git.kernel.org/stable/c/cbfa059dfb48b9aa322e34fd44a093d9ca29ad7e https://git.kernel.org/stable/c/baf56975806534268e24acf9a8abb1c447ce11e9
