Between 1999 and 2024, NIST assigned more than 20,000 CVEs to the Linux kernel. The pace has accelerated in recent years, partly due to the kernel team\u2019s own decision in 2024 to register CVEs more aggressively for even minor fixes.<\/p>\n<p>Annual CVE counts for the Linux kernel have grown steadily since 2019, with a particularly steep increase between 2023 and 2024.<\/p>\n<table>\n<tr>\n<th>Year<\/th>\n<th>Total CVEs<\/th>\n<th>Year-over-Year Change<\/th>\n<\/tr>\n<tr>\n<td>2019<\/td>\n<td>594<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<tr>\n<td>2020<\/td>\n<td>693<\/td>\n<td>+16.7%<\/td>\n<\/tr>\n<tr>\n<td>2021<\/td>\n<td>812<\/td>\n<td>+17.2%<\/td>\n<\/tr>\n<tr>\n<td>2022<\/td>\n<td>1,064<\/td>\n<td>+31.0%<\/td>\n<\/tr>\n<tr>\n<td>2023<\/td>\n<td>1,736<\/td>\n<td>+63.2%<\/td>\n<\/tr>\n<tr>\n<td>2024<\/td>\n<td>3,108<\/td>\n<td>+79.0%<\/td>\n<\/tr>\n<\/table>\n<p class=\"source-line\">Source: NIST National Vulnerability Database (NVD)<\/p>\n<h2>CVE Severity Distribution in Linux (2024)<\/h2>\n<p>Using the CVSS v3.1 scoring system, the majority of Linux kernel CVEs in 2024 fell into the High category.
