CVE-2026-23178 Detail
Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionIn 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->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->bufsize - sizeof(__le16)`. The impact is low since access to hidraw devices requires root. Metrics
