| CVE-2026-42512 | 1 Freebsd | 1 Freebsd | 2026-05-01 | 8.1 High |
| As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers. The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun. A specially crafted packet can cause dhclient to overrun its buffer of environment entries. This can result in a crash, but it may be possible to leverage this bug to achieve remote code execution. | ||||
| CVE-2026-42511 | 1 Freebsd | 1 Freebsd | 2026-05-01 | 8.1 High |
| The BOOTP file field is written to the lease file without escaping embedded double-quotes, allowing injection of arbitrary dhclient.conf directives. When the lease file is subsequently re-parsed by dhclient, e.g., after a system restart, an attacker-controlled field from the lease is passed to dhclient-script(8), which evaluates it. A rogue DHCP server may be able to execute arbirary code as root on a system running dhclient. | ||||
| CVE-2026-5398 | 1 Freebsd | 1 Freebsd | 2026-05-01 | 8.4 High |
| The implementation of TIOCNOTTY failed to clear a back-pointer from the structure representing the controlling terminal to the calling process' session. If the invoking process then exits, the terminal structure may end up containing a pointer to freed memory. A malicious process can abuse the dangling pointer to grant itself root privileges. | ||||
| CVE-2026-6386 | 1 Freebsd | 1 Freebsd | 2026-05-01 | 6.2 Medium |
| 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) interface. In particular, it would always treat a page directory page entry as pointing to another page table page. The bug can be abused by an unprivileged user to cause pmap_pkru_update_range() to treat userspace memory as a page table page, and thus overwrite memory to which the application would otherwise not have access. | ||||
| CVE-2026-7164 | 1 Freebsd | 1 Freebsd | 2026-05-01 | 7.5 High |
| Incorrect packet validation allowed unbounded recursion parsing SCTP chunk parameters. This can eventually result in a stack overflow and panic. Remote attackers can craft packets which cause affected systems to panic. This affects any system where pf is configured to process traffic, independent of the configured ruleset. | ||||
| CVE-2026-39457 | 1 Freebsd | 1 Freebsd | 2026-05-01 | 7.8 High |
| When exchanging data over a socket, libnv uses select(2) to wait for data to arrive. However, it does not verify whether the provided socket descriptor fits in select(2)'s file descriptor set size limit of FD_SETSIZE (1024). An attacker who is able to force a libnv application to allocate large file descriptors, e.g., by opening many descriptors and executing a program which is not careful to close them upon startup, can trigger stack corruption. If the target application is setuid-root, then this could be used to elevate local privileges. | ||||
| CVE-2026-4652 | 1 Freebsd | 1 Freebsd | 2026-04-30 | 7.5 High |
| On a system exposing an NVMe/TCP target, a remote client can trigger a kernel panic by sending a CONNECT command for an I/O queue with a bogus or stale CNTLID. An attacker with network access to the NVMe/TCP target can trigger an unauthenticated Denial of Service condition on the affected machine. | ||||
| CVE-2026-4247 | 1 Freebsd | 1 Freebsd | 2026-04-30 | 7.5 High |
| When a challenge ACK is to be sent tcp_respond() constructs and sends the challenge ACK and consumes the mbuf that is passed in. When no challenge ACK should be sent the function returns and leaks the mbuf. If an attacker is either on path with an established TCP connection, or can themselves establish a TCP connection, to an affected FreeBSD machine, they can easily craft and send packets which meet the challenge ACK criteria and cause the FreeBSD host to leak an mbuf for each crafted packet in excess of the configured rate limit settings i.e. with default settings, crafted packets in excess of the first 5 sent within a 1s period will leak an mbuf. Technically, off-path attackers can also exploit this problem by guessing the IP addresses, TCP port numbers and in some cases the sequence numbers of established connections and spoofing packets towards a FreeBSD machine, but this is harder to do effectively. | ||||
| CVE-2025-24934 | 1 Freebsd | 1 Freebsd | 2026-04-24 | 5.4 Medium |
| 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 connect(2) and implied connect via sendto(2), and may leave the application vulnerable to spoofing attacks. The kernel failed to check the connection state of sockets when adding them to load-balancing groups. Furthermore, when looking up the destination socket for an incoming packet, the kernel will match a socket belonging to a load-balancing group even if it is connected, in violation of the contract that connected sockets are only supposed to receive packets originating from the connected host. | ||||
| CVE-2007-0166 | 1 Freebsd | 1 Freebsd | 2026-04-23 | N/A |
| The jail rc.d script in FreeBSD 5.3 up to 6.2 does not verify pathnames when writing to /var/log/console.log during a jail start-up, or when file systems are mounted or unmounted, which allows local root users to overwrite arbitrary files, or mount/unmount files, outside of the jail via a symlink attack. | ||||
| CVE-2009-1436 | 1 Freebsd | 1 Freebsd | 2026-04-23 | N/A |
| The db interface in libc in FreeBSD 6.3, 6.4, 7.0, 7.1, and 7.2-PRERELEASE does not properly initialize memory for Berkeley DB 1.85 database structures, which allows local users to obtain sensitive information by reading a database file. | ||||
| CVE-2008-4247 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2026-04-23 | N/A |
| ftpd in OpenBSD 4.3, FreeBSD 7.0, NetBSD 4.0, Solaris, and possibly other operating systems interprets long commands from an FTP client as multiple commands, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and execute arbitrary FTP commands via a long ftp:// URI that leverages an existing session from the FTP client implementation in a web browser. | ||||
| CVE-2009-2649 | 1 Freebsd | 1 Freebsd | 2026-04-23 | N/A |
| The IATA (ata) driver in FreeBSD 6.0 and 8.0, when read access to /dev is available, allows local users to cause a denial of service (kernel panic) via a certain IOCTL request with a large count, which triggers a malloc call with a large value. | ||||
| CVE-2009-4502 | 3 Freebsd, Sun, Zabbix | 3 Freebsd, Solaris, Zabbix | 2026-04-23 | N/A |
| The NET_TCP_LISTEN function in net.c in Zabbix Agent before 1.6.7, when running on FreeBSD or Solaris, allows remote attackers to bypass the EnableRemoteCommands setting and execute arbitrary commands via shell metacharacters in the argument to net.tcp.listen. NOTE: this attack is limited to attacks from trusted IP addresses. | ||||
| CVE-2009-1041 | 1 Freebsd | 1 Freebsd | 2026-04-23 | N/A |
| The ktimer feature (sys/kern/kern_time.c) in FreeBSD 7.0, 7.1, and 7.2 allows local users to overwrite arbitrary kernel memory via an out-of-bounds timer value. | ||||
| CVE-2008-4609 | 12 Bsd, Bsdi, Cisco and 9 more | 22 Bsd, Bsd Os, Catalyst Blade Switch 3020 and 19 more | 2026-04-23 | N/A |
| The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress. | ||||
| CVE-2009-4147 | 1 Freebsd | 1 Freebsd | 2026-04-23 | N/A |
| The _rtld function in the Run-Time Link-Editor (rtld) in libexec/rtld-elf/rtld.c in FreeBSD 7.1 and 8.0 does not clear the (1) LD_LIBMAP, (2) LD_LIBRARY_PATH, (3) LD_LIBMAP_DISABLE, (4) LD_DEBUG, and (5) LD_ELF_HINTS_PATH environment variables, which allows local users to gain privileges by executing a setuid or setguid program with a modified variable containing an untrusted search path that points to a Trojan horse library, different vectors than CVE-2009-4146. | ||||
| CVE-2007-3722 | 1 Freebsd | 1 Freebsd | 2026-04-23 | N/A |
| The 4BSD process scheduler in the FreeBSD kernel performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service (CPU consumption) by performing voluntary nanosecond sleeps that result in the process not being active during a clock interrupt, as described in "Secretly Monopolizing the CPU Without Superuser Privileges." | ||||
| CVE-2007-4304 | 2 Cerb, Freebsd | 2 Cerbng, Freebsd | 2026-04-23 | N/A |
| CerbNG for FreeBSD 4.8 does not properly implement VM protection when attempting to prevent system call wrapper races, which allows local users to have an unknown impact related to an "incorrect write protection of pages". | ||||
| CVE-2008-1147 | 8 Apple, Cosmicperl, Darwin and 5 more | 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more | 2026-04-23 | N/A |
| A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting. | ||||
