squid: Squid: Denial of Service via heap Use-After-Free vulnerability in ICP handling
A flaw was found in Squid. A remote attacker can exploit a heap Use-After-Free vulnerability when handling ICP Internet Cache Protocol traffic. This allows them to perform a reliable and repeatable Denial of Service DoS attack, making the Squid service unavailable. This attack is limited to...
Squid: Squid: Denial of Service via crafted ICP traffic
A flaw was found in Squid. A remote attacker can exploit this vulnerability by sending specially crafted ICP Internet Cache Protocol traffic. This can lead to a Denial of Service DoS due to premature resource release and use-after-free vulnerabilities. This attack is possible in Squid deployments...
EUVD-2026-26276
Integer underflow in the ICMP and ICMPv6 echo reply handlers in FreeRTOS-Plus-TCP before V4.4.1 and V4.2.6 allows an adjacent network user to cause a denial of service device crash when outgoing ping support is enabled, because header sizes are subtracted from a packet length field without...
CVE-2026-7422 MAC Address Validation Bypass in FreeRTOS-Plus-TCP IPv4 and IPv6 Packet Processing
Insufficient packet validation in FreeRTOS-Plus-TCP before V4.2.6 and V4.4.1 allows an adjacent network actor to bypass all checksum and minimum-size validation by spoofing the Ethernet source MAC address to match one of the device's own registered endpoints, because the loopback detection...
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...

Bad Bot Report 2026: The Internet Is No Longer Human and It’s Changing How Business Works
For decades, companies have operated on a simple assumption that most internet traffic came from people. That assumption no longer holds. The latest 2026 Bad Bot Report: Bad Bots in the Agentic Age reinforces a shift that is now impossible to ignore. Automated traffic continues to outpace human...
Linux IPv6 Kernel Heap Buffer Overflow DoS
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...
CLSA-2026-1777392877 cups: Fix of CVE-2026-34980
CVE-2026-34980: filter control characters from IPP option values and allowlist PPD keywords returned by filters so a remote attacker cannot inject cupsFilter/cupsFilter2 entries on a shared PostScript queue and gain code execution as the cupsd user...
What Anthropic’s Mythos Means for the Future of Cybersecurity
Two weeks ago, Anthropic announced that its new model, Claude Mythos Preview, can autonomously find and weaponize software vulnerabilities, turning them into working exploits without expert guidance. These were vulnerabilities in key software like operating systems and internet infrastructure tha...
