{"schema":"threatline.record/2","record":{"id":"CVE-2026-98612","aliases":[],"summary":"net: usb: catc: bound the RX packet length in catc_rx_done()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: usb: catc: bound the RX packet length in catc_rx_done()\n\ncatc_rx_done() walks a multi-packet URB, reading a two-byte length from\neach packet header. Its bound, pkt_len > urb->actual_length, ignores the\nheader offset and compares against the whole transfer rather than the\nbytes left from pkt_start, so a crafted packet header makes\nskb_copy_to_linear_data() read past the buffer.\n\nA length below ETH_HLEN is also accepted, including zero, and\neth_type_trans() then reads a MAC header from the uninitialised tailroom\nof a shorter skb. The is_f5u011 branch takes its length straight from\nthe transfer, so a zero-length URB reaches the same path.\n\nTrack the bytes remaining from the current packet, and reject a header\nthat does not fit, a length past what is left, and a length below an\nEthernet header.\n\nA transfer shorter than an Ethernet header, including a zero-length one,\npreviously became a runt skb passed to netif_rx() and counted as\nreceived; it is now counted in rx_length_errors and ends the walk.","categories":["Operating
