CVE-2026-64351

CVE-2026-64351 affects the Linux kernel USB Kalmia driver (kalmia_rx_fixup). The bug computes usb_packet_length as skb->len - (2 * KALMIA_HEADER_LENGTH) without ensuring both framing headers are present on every loop iteration. This can allow a short bulk-IN frame to underflow usb_packet_lengt...

CVE-2026-64351 net: usb: kalmia: bound RX frame length in kalmia_rx_fixup()

In the Linux kernel, the following vulnerability has been resolved: net: usb: kalmia: bound RX frame length in kalmiarxfixup kalmiarxfixup computes usbpacketlength = skb-len - 2 KALMIAHEADERLENGTH as a u16, guarded only by a pre-loop check that skb-len is at least KALMIAHEADERLENGTH, which is 6. ...
