| CVE-2026-3038 | 1 Freebsd | 1 Freebsd | 2026-04-16 | 7.5 High |
| The rtsock_msg_buffer() function serializes routing information into a buffer. As a part of this, it copies sockaddr structures into a sockaddr_storage structure on the stack. It assumes that the source sockaddr length field had already been validated, but this is not necessarily the case, and it's possible for a malicious userspace program to craft a request which triggers a 127-byte overflow. In practice, this overflow immediately overwrites the canary for the rtsock_msg_buffer() stack frame, resulting in a panic once the function returns. The bug allows an unprivileged user to crash the kernel by triggering a stack buffer overflow in rtsock_msg_buffer(). In particular, the overflow will corrupt a stack canary value that is verified when the function returns; this mitigates the impact of the stack overflow by triggering a kernel panic. Other kernel bugs may exist which allow userspace to find the canary value and thus defeat the mitigation, at which point local privilege escalation may be possible. | ||||
| CVE-2026-2261 | 1 Freebsd | 1 Freebsd | 2026-04-16 | 7.5 High |
| Due to a programming error, blocklistd leaks a socket descriptor for each adverse event report it receives. Once a certain number of leaked sockets is reached, blocklistd becomes unable to run the helper script: a child process is forked, but this child dereferences a null pointer and crashes before it is able to exec the helper. At this point, blocklistd still records adverse events but is unable to block new addresses or unblock addresses whose database entries have expired. Once a second, much higher number of leaked sockets is reached, blocklistd becomes unable to receive new adverse event reports. An attacker may take advantage of this by triggering a large number of adverse events from sacrificial IP addresses to effectively disable blocklistd before launching an attack. Even in the absence of attacks or probes by would-be attackers, adverse events will occur regularly in the course of normal operations, and blocklistd will gradually run out file descriptors and become ineffective. The accumulation of open sockets may have knock-on effects on other parts of the system, resulting in a general slowdown until blocklistd is restarted. | ||||

| CVE-1999-0783 | 1 Freebsd | 1 Freebsd | 2026-04-16 | 5.5 Medium |
| FreeBSD allows local users to conduct a denial of service by creating a hard link from a device special file to a file on an NFS file system. | ||||
| CVE-2005-0988 | 7 Freebsd, Gentoo, Gnu and 4 more | 13 Freebsd, Linux, Gzip and 10 more | 2026-04-16 | N/A |
| Race condition in gzip 1.2.4, 1.3.3, and earlier, when decompressing a gzipped file, allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by gzip after the decompression is complete. | ||||
| CVE-2001-0310 | 1 Freebsd | 1 Freebsd | 2026-04-16 | N/A |
| sort in FreeBSD 4.1.1 and earlier, and possibly other operating systems, uses predictable temporary file names and does not properly handle when the temporary file already exists, which causes sort to crash and possibly impacts security-sensitive scripts. | ||||
