| CVE-2026-49428 | Hig | 0.48 | 8.4 | 0.00 | Aug 19, 2026 | Certain system calls, such open(2) with the O_TRUNC flag set, and fspacectl(2), could incorrectly free memory in largepage objects. These operations are not permitted on largepage objects, but the implementation did not verify this. An unprivileged local user can abuse the bug… | ||

| CVE-2026-45253 | Hig | 0.48 | 8.4 | 0.00 | May 21, 2026 | ptrace(PT_SC_REMOTE) failed to properly validate parameters for the syscall(2) and __syscall(2) meta-system calls.

| CVE-2019-14899 | Hig | 0.48 | 7.4 | 0.01 | Dec 11, 2019 | A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct… | ||
| CVE-2026-58086 | Hig | 0.46 | 8.1 | 0.00 | Aug 19, 2026 | As an inadvertent side effect of an unrelated code change, PRIV_KTRACE was always denied to a jailed root user. Tracing configured by a jailed root user was therefore not flagged as privileged. An unprivileged user in a jail that has permission to debug the target process can… | ||
| CVE-2026-42511 | Hig | 0.46 | 8.1 | 0.00 | Apr 30, 2026 | The BOOTP file field is written to the lease file without escaping embedded double-quotes, allowing injection of arbitrary dhclient.conf directives.

| CVE-2023-5369 | Hig | 0.46 | 7.1 | 0.00 | Oct 4, 2023 | Before correction, the copy_file_range system call checked only for the CAP_READ and CAP_WRITE capabilities on the input and output file descriptors, respectively. Using an offset is logically equivalent to seeking, and the system call must additionally require the CAP_SEEK… | ||

| CVE-2020-1967 | Hig | 0.46 | 7.5 | 0.53 | Apr 21, 2020 | Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or… | ||
| CVE-2018-6924 | Hig | 0.46 | 7.1 | 0.00 | Sep 12, 2018 | In FreeBSD before 11.1-STABLE, 11.2-RELEASE-p3, 11.1-RELEASE-p14, 10.4-STABLE, and 10.4-RELEASE-p12, insufficient validation in the ELF header parser could allow a malicious ELF binary to cause a kernel crash or disclose kernel memory. | ||
| CVE-2008-5162 | Hig | 0.46 | 7.0 | 0.00 | Nov 26, 2008 | The arc4random function in the kernel in FreeBSD 6.3 through 7.1 does not have a proper entropy source for a short time period immediately after boot, which makes it easier for attackers to predict the function's return values and conduct certain attacks against the GEOM… | ||
| CVE-2026-58094 | Hig | 0.44 | 7.8 | 0.00 | Aug 26, 2026 | The FIOSSHMLPGCNF ioctl(2) operation configures the page size for a largepage shared memory object. This is intended to be used immediately after creating the object, before any memory is allocated for the object. The handler checked whether a page size had already been… | ||
