In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: usb: sr9700: include receive overhead in the length check<\/p>\n
The receive fixup subtracts the Ethernet CRC from the reported packet
\nlength, but compares that payload length against the whole remaining
\nreceive buffer. The following copy starts after the three-byte header,
\nand the cursor advance consumes both that header and the four-byte CRC.<\/p>\n
Require the payload to fit after SR_RX_OVERHEAD before copying it or
\nadvancing to the next packet. The loop already ensures that the
\nremaining buffer is larger than the overhead, so the subtraction is
\nsafe.<\/p>\n
