CVE-2026-43136

A flaw was found in the Linux kernel's Human Interface Device (HID) subsystem, specifically within the logitech-hidpp driver. A remote attacker, by connecting a specially crafted Universal Serial Bus (USB) device, could send malformed HID report descriptors that lack valid fields. This could lead to a kernel crash, resulting in a Denial of Service (DoS) for the affected system.

Red Hat acknowledges the upstream Linux kernel correction for «HID» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the hid_logitech_hidpp module from being loaded. See https://access.redhat.com/solutions/41278 for instructions.
