CVE-2009-4538

31
FAUCET Score

CVE-2009-4538 is a critical vulnerability in the e1000e driver of the Linux kernel, affecting versions 2.6.32.3 and earlier, including Debian distributions. It stems from improper size checking of Ethernet frames exceeding the MTU, allowing remote attackers to achieve an unspecified but potentially severe impact. With a CVSS score of 10.0, this vulnerability presents a high-risk scenario due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, its high FAUCET Risk Score of 86/100 indicates a substantial inherent risk.
