Описание
In the Linux kernel, the following vulnerability has been resolved:
HID: logitech-hidpp: Check maxfield in hidpp_get_report_length()
Do not crash when a report has no fields.
Fake USB gadgets can send their own HID report descriptors and can define report
structures without valid fields. This can be used to crash the kernel over USB.
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.
Отчет
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.
Меры по смягчению последствий
To mitigate this issue, prevent the hid_logitech_hidpp module from being loaded. See https://access.redhat.com/solutions/41278 for instructions.
