CVE-2024-53082

Guest kernel compromise via oversized RSS key

Published Nov 19, 2024 · Updated Aug 5, 2026

Out-of-bounds access in Linux virtio_net 5.18 through 6.12-rc6 allows attackers to read or overwrite kernel memory or crash the guest. virtnet_probe() accepts a device-supplied rss_max_key_size larger than the fixed 40-byte RSS key array, and later fill and copy operations cross that boundary. Attackers controlling a virtio network device or backend can trigger the flaw during driver probing without guest credentials or user interaction.
