CVE-2026-64540

The CVE-2026-64540 issue affects the Linux kernel usbnet driver for GeneLink GL620A. A vulnerability in genelink_rx_fixup() could allow an out-of-bounds read by splitting an aggregated RX frame and using per-packet lengths that aren’t checked against the received data, enabling a malicious GL620A...

CVE-2026-64540 usbnet: gl620a: fix out-of-bounds read in genelink_rx_fixup()

In the Linux kernel, the following vulnerability has been resolved: usbnet: gl620a: fix out-of-bounds read in genelinkrxfixup genelinkrxfixup splits an aggregated RX frame into its individual packets, using a per-packet length taken from device-supplied data. That length is only bounded by...

CVE-2026-64531

CVE-2026-64531 describes a Linux kernel issue in net/openvswitch: generated flow actions stored as nlattrs can exceed the 16-bit nla_len, allowing an oversized container to be closed with a truncated length. The fix preserves large total-action streams but rejects nested action containers that do...
