| CVE-2025-24934 | Med | 0.35 | 5.4 | 0.00 | Oct 22, 2025 | Software which sets SO_REUSEPORT_LB on a socket and then connects it to a host will not directly observe any problems. However, due to its membership in a load-balancing group, that socket will receive packets originating from any host. This breaks the contract of the… | ||
| CVE-2018-6922 | Med | 0.35 | 5.3 | 0.03 | Aug 9, 2018 | One of the data structures that holds TCP segments in all versions of FreeBSD prior to 11.2-RELEASE-p1, 11.1-RELEASE-p12, and 10.4-RELEASE-p10 uses an inefficient algorithm to reassemble the data. This causes the CPU time spent on segment processing to grow linearly with the… | ||

| CVE-2006-0054 | Med | 0.35 | 5.3 | 0.03 | Jan 11, 2006 | The ipfw firewall in FreeBSD 6.0-RELEASE allows remote attackers to cause a denial of service (firewall crash) via ICMP IP fragments that match a reset, reject or unreach action, which leads to an access of an uninitialized pointer. | ||
| CVE-2024-39281 | Med | 0.34 | 5.3 | 0.00 | Nov 12, 2024 | The command ctl_persistent_reserve_out allows the caller to specify an arbitrary size which will be passed to the kernel's memory allocator. | ||
| CVE-2026-6386 | Med | 0.33 | 6.2 | 0.00 | Apr 22, 2026 | In order to apply a particular protection key to an address range, the kernel must update the corresponding page table entries. The subroutine which handled this failed to take into account the presence of 1GB largepage mappings created using the shm_create_largepage(3)… | ||
| CVE-2025-0662 | Med | 0.32 | 4.9 | 0.00 | Jan 30, 2025 | In some cases, the ktrace facility will log the contents of kernel structures to userspace. In one such case, ktrace dumps a variable-sized sockaddr to userspace. There, the full sockaddr is copied, even when it is shorter than the full size. This can result in up to 14… | ||
| CVE-2017-1088 | Low | 0.21 | 3.3 | 0.00 | Nov 16, 2017 | In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p4, 11.0-RELEASE-p15, 10.4-STABLE, 10.4-RELEASE-p3, and 10.3-RELEASE-p24, the kernel does not properly clear the memory of the kld_file_stat structure before filling the data. Since the structure filled by the kernel is allocated on… | ||
| CVE-2017-1086 | Low | 0.21 | 3.3 | 0.00 | Nov 16, 2017 | In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p4, 11.0-RELEASE-p15, 10.4-STABLE, 10.4-RELEASE-p3, and 10.3-RELEASE-p24, not all information in the struct ptrace_lwpinfo is relevant for the state of any thread, and the kernel does not fill the irrelevant bytes or short strings.… | ||
| CVE-2005-0356 | 0.10 | — | 0.83 | May 31, 2005 | Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later… | |||
| CVE-2003-0001 | 0.09 | — | 0.73 | Jan 17, 2003 | Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets, as demonstrated by Etherleak. | |||
| CVE-1999-0513 | 0.09 | — | 0.70 | Jan 5, 1998 | ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service. | |||
| CVE-2006-0900 | 0.08 | — | 0.64 | Feb 27, 2006 | nfsd in FreeBSD 6.0 kernel allows remote attackers to cause a denial of service via a crafted NFS mount request, as demonstrated by the ProtoVer NFS test suite. | |||

A lack of quoting meant that… |
