ovn: ovn: Heap Over-Read in ICMP Error Response Generation
When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length iptotlen for IPv4, ip6plen for IPv6 without validating it against the actual packet buffer size...
The vulnerability of the rt6_nlmsg_size() function in the net/ipv6/route.c module of the Linux operating system’s IPv6 kernel implementation allows a attacker to cause a service failure.
The vulnerability of the rt6nlmsgsize function in the net/ipv6/route.c module of the Linux operating system’s IPv6 kernel implementation is related to incorrect calculation of the buffer size. Exploiting this vulnerability could allow an attacker to cause a service failure...
net/url: Incorrect parsing of IPv6 host literals in net/url
The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: flowlabel: defer exclusive option free until RCU teardown ip6flseqshow walks the global flowlabel hash under the seq-file RCU read-side lock and prints fl-opt-optnflen when an option block is present. Exclusive...
CVE-2026-31669
A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...
CVE-2026-31630 rxrpc: proc: size address buffers for %pISpc output
In the Linux kernel, the following vulnerability has been resolved: rxrpc: proc: size address buffers for %pISpc output The AFRXRPC procfs helpers format local and remote socket addresses into fixed 50-byte stack buffers with "%pISpc". That is too small for the longest current-tree IPv6-with-port...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the AFRXRPC procfs helper function using a fixed 50-byte stack buffer to format addresses. Howeve...
OVN 安全漏洞
OVN is an open-source data center virtualization platform based on virtual network technology. OVN has a security vulnerability that arises from the lack of verification of the total length of the IP header declaration and the actual packet buffer size when generating ICMP error responses. This c...

EUVD-2018-21782
Angry IP Scanner 3.5.3 contains a buffer overflow vulnerability in the preferences dialog that allows local attackers to crash the application by supplying an excessively large string. Attackers can generate a file containing a massive buffer of repeated characters and paste it into the unavailab...
CVE-2026-31472
CVE-2026-31472 concerns the Linux kernel, specifically the xfrm/ IPTFS path. A crafted ESP packet with an inner IPv4 header can cause an infinite loop in __input_process_payload() if the inner header has tot_len=0 or malformed ihl. The fix adds validation to reject inner packets where tot_len <...

cpython: IMAP command injection in user-controlled commands
A flaw was found in the imaplib module in the Python standard library. The imaplib module does not reject control characters, such as newlines, in user-controlled input passed to IMAP commands. This issue allows an attacker to inject additional commands to be executed in the IMAP server...
CVE-2026-41285
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 "ndoptlen 8 - 2" expression with no preceding check for whether ndoptlen is zero...
