CVE-2019-11683

34
FAUCET Score

CVE-2019-11683 is a critical denial-of-service vulnerability affecting Linux kernel versions 5.x prior to 5.0.13, including Canonical and Ubuntu distributions. This flaw, dubbed "GRO packet of death," allows remote attackers to trigger slab-out-of-bounds memory corruption by sending specially crafted UDP packets with a zero payload, potentially leading to system instability or other unspecified impacts. With a CVSS score of 9.8, it is easily exploitable over the network without user interaction or privileges. While no public exploit code or active exploitation has been observed, its high EPSS and FAUCET Risk Score indicate a significant potential for future exploitation.
