| CVE-2023-52556 | Med | 0.00 | 6.2 | 0.00 | Mar 1, 2024 | In OpenBSD 7.4 before errata 009, a race condition between pf(4)'s processing of packets and expiration of packet states may cause a kernel panic. | ||
| CVE-2023-40216 | Med | 0.00 | 5.5 | 0.00 | Aug 10, 2023 | OpenBSD 7.3 before errata 014 is missing an argument-count bounds check in console terminal emulation. This could cause incorrect memory access and a kernel crash after receiving crafted DCS or CSI terminal escape sequences. | ||
| CVE-2023-35784 | Cri | 0.00 | 9.8 | 0.01 | Jun 16, 2023 | A double free or use after free could occur after SSL_clear in OpenBSD 7.2 before errata 026 and 7.3 before errata 004, and in LibreSSL before 3.6.3 and 3.7.x before 3.7.3. NOTE: OpenSSL is not affected. | ||
