| CVE-2026-56101 | 1 Openbsd | 1 Openbsd | 2026-09-08 | 5.3 Medium |
| OpenBSD before commit 1ee99df contains an inverted comparison vulnerability in the ieee80211_michael_mic_failure() function within sys/net80211/ieee80211_crypto_tkip.c that allows unauthenticated attackers within RF range to trigger denial of service by sending two malformed TKIP frames separated by more than 60 seconds. Attackers can exploit the reversed TKIP MIC failure countermeasure window check to deauthenticate all associated TKIP stations and block reassociation for up to 90 seconds, while within-window MIC failures that should engage countermeasures are silently discarded, leaving key-recovery attempts undetected. | ||||
| CVE-2026-57589 | 1 Openbsd | 1 Openbsd | 2026-06-25 | 7.4 High |
| sys/kern/sysv_sem.c in OpenBSD through 7.9 has a use-after-free allowing local privilege escalation to root. This is a context switch use-after-free after tsleep in sys_semget(). | ||||
| CVE-2026-56099 | 1 Openbsd | 2 Openbsd, Src | 2026-06-23 | 5.3 Medium |
| OpenBSD before commit 6a23123 (2026-06-18) contains an out-of-bounds read vulnerability in the mpls_do_error function within sys/netmpls/mpls_input.c that allows remote attackers to disclose kernel stack memory by sending crafted MPLS frames with 16 labels and no Bottom-of-Stack bit set. | ||||
| CVE-2026-55706 | 1 Openbsd | 1 Openbsd | 2026-06-17 | 5.8 Medium |
| sppp_pap_input in sys/net/if_spppsubr.c in OpenBSD before 076e2b1 allows authentication bypass via certain zero values for lengths. | ||||
| CVE-2026-41285 | 1 Openbsd | 1 Openbsd | 2026-04-28 | 4.3 Medium |
| In OpenBSD through 7.8, the slaacd and rad daemons have an infinite loop when they receive a crafted ICMPv6 Neighbor Discovery (ND) option (over a local network) with length zero, because of an "nd_opt_len * 8 - 2" expression with no preceding check for whether nd_opt_len is zero. | ||||
| 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-2006-6397 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2026-04-23 | N/A |
| Integer overflow in banner/banner.c in FreeBSD, NetBSD, and OpenBSD might allow local users to modify memory via a long banner. NOTE: CVE and multiple third parties dispute this issue. Since banner is not setuid, an exploit would not cross privilege boundaries in normal operations. This issue is not a vulnerability | ||||
| CVE-2008-1057 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| The ip6_check_rh0hdr function in netinet6/ip6_input.c in OpenBSD 4.2 allows attackers to cause a denial of service (panic) via malformed IPv6 routing headers. | ||||
| CVE-2008-2476 | 6 Force10, Freebsd, Juniper and 3 more | 6 Ftos, Freebsd, Jnos and 3 more | 2026-04-23 | N/A |
| The IPv6 Neighbor Discovery Protocol (NDP) implementation in (1) FreeBSD 6.3 through 7.1, (2) OpenBSD 4.2 and 4.3, (3) NetBSD, (4) Force10 FTOS before E7.7.1.1, (5) Juniper JUNOS, and (6) Wind River VxWorks 5.x through 6.4 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB). | ||||
| CVE-2007-0343 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| OpenBSD before 20070116 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via certain IPv6 ICMP (aka ICMP6) echo request packets. | ||||
| CVE-2007-1351 | 7 Mandrakesoft, Openbsd, Redhat and 4 more | 11 Mandrake Linux, Mandrake Linux Corporate Server, Mandrake Multi Network Firewall and 8 more | 2026-04-23 | N/A |
| Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 20070403 and (2) freetype 2.3.2 and earlier allows remote authenticated users to execute arbitrary code via crafted BDF fonts, which result in a heap overflow. | ||||
| CVE-2006-5218 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2026-04-23 | N/A |
| Integer overflow in the systrace_preprepl function (STRIOCREPLACE) in systrace in OpenBSD 3.9 and NetBSD 3 allows local users to cause a denial of service (crash), gain privileges, or read arbitrary kernel memory via large numeric arguments to the systrace ioctl. | ||||
| CVE-2006-6730 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2026-04-23 | N/A |
| OpenBSD and NetBSD permit usermode code to kill the display server and write to the X.Org /dev/xf86 device, which allows local users with root privileges to reduce securelevel by replacing the System Management Mode (SMM) handler via a write to an SMRAM address within /dev/xf86 (aka the video card memory-mapped I/O range), and then launching the new handler via a System Management Interrupt (SMI), as demonstrated by a write to Programmed I/O port 0xB2. | ||||
| CVE-2006-6164 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| The _dl_unsetenv function in loader.c in the ELF ld.so in OpenBSD 3.9 and 4.0 does not properly remove duplicate environment variables, which allows local users to pass dangerous variables such as LD_PRELOAD to loading processes, which might be leveraged to gain privileges. | ||||
| CVE-2007-6700 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| Cross-site scripting (XSS) vulnerability in cgi-bin/bgplg in the web interface for the BGPD daemon in OpenBSD 4.1 allows remote attackers to inject arbitrary web script or HTML via the cmd parameter. | ||||
| CVE-2007-1365 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| Buffer overflow in kern/uipc_mbuf2.c in OpenBSD 3.9 and 4.0 allows remote attackers to execute arbitrary code via fragmented IPv6 packets due to "incorrect mbuf handling for ICMP6 packets." NOTE: this was originally reported as a denial of service. | ||||
| CVE-2008-1058 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| The tcp_respond function in netinet/tcp_subr.c in OpenBSD 4.1 and 4.2 allows attackers to cause a denial of service (panic) via crafted TCP packets. NOTE: some of these details are obtained from third party information. | ||||
| CVE-2008-0384 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| OpenBSD 4.2 allows local users to cause a denial of service (kernel panic) by calling the SIOCGIFRTLABEL IOCTL on an interface that does not have a route label, which triggers a NULL pointer dereference when the return value from the rtlabel_id2name function is not checked. | ||||
| CVE-2007-5365 | 5 Debian, Openbsd, Redhat and 2 more | 7 Debian Linux, Openbsd, Enterprise Linux and 4 more | 2026-04-23 | N/A |
| Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU. | ||||
| CVE-2007-4305 | 5 Netbsd, Openbsd, Sysjail and 2 more | 5 Netbsd, Openbsd, Sysjail and 2 more | 2026-04-23 | N/A |
| Multiple race conditions in the (1) Sudo monitor mode and (2) Sysjail policies in Systrace on NetBSD and OpenBSD allow local users to defeat system call interposition, and consequently bypass access control policy and auditing. | ||||
