How to fix?

Upgrade Debian:11 linux-6.1 to version 6.1.164-1~deb11u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-6.1 package and not the linux-6.1 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

HID: i2c-hid: fix potential buffer overflow in i2c_hid_get_report()

i2c_hid_xfer is used to read recv_len + sizeof(__le16) bytes of data into ihid-&gt;rawbuf.

The former can come from the userspace in the hidraw driver and is only bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set max_buffer_size field of struct hid_ll_driver which we do not).

The latter has size determined at runtime by the maximum size of different report types you could receive on any particular device and can be a much smaller value.

Fix this by truncating recv_len to ihid-&gt;bufsize - sizeof(__le16).

The impact is low since access to hidraw devices requires root.
