CVE-2026-98597

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

net: usb: sr9700: include receive overhead in the length check

The receive fixup subtracts the Ethernet CRC from the reported packet

length, but compares that payload length against the whole remaining

receive buffer. The following copy starts after the three-byte header,

and the cursor advance consumes both that header and the four-byte CRC.

Require the payload to fit after SR_RX_OVERHEAD before copying it or

advancing to the next packet. The loop already ensures that the

remaining buffer is larger than the overhead, so the subtraction is

safe.

The issue was found by our static-analysis tool.
