CVE-2026-72712

Nmap versions up to and including 7.99 contains a denial of service vulnerability that allows remote attackers to crash the application by sending a crafted packet containing a zero-length TCP option. The malformed packet forces the Packet:parseoptions function in nselib/packet.lua to allocate...

CVE-2026-68369

A flaw was found in the Linux kernel's USB gadget printer driver. An attacker, by providing specific input to the printerread function, could trigger an infinite loop. This vulnerability occurs when the copytouser function fails to copy data, leading to a denial of service condition where the...

CVE-2026-72522

A flaw in libexpat's toUtf16 functions mishandles Unicode low surrogates by treating them as high surrogates. An attacker can exploit the resulting out-of-bounds read to trigger an infinite loop, causing a denial of service DoS. Mitigation Limit exposure by restricting the parsing of untrusted or...

CVE-2026-68313

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. A vulnerability in the tipcnlcompatdumpit function can lead to an infinite loop if a callback returns a negative error code. This prevents the release of a critical system lock, causing other processes to...

tar: Node-tar: Denial of Service via malformed tar archive header

A flaw was found in node-tar, a tar archive manipulation library for Node.js. A remote attacker could exploit this vulnerability by providing a specially crafted tar archive with a negative entry size in its header. This malformed header causes the archive scanner to enter an infinite loop,...

CVE-2026-67213

A flaw was found in nanoid Nano ID, a small, secure, and URL-friendly unique string ID generator. An attacker could exploit this vulnerability by providing a zero-size input to the customAlphabet or customRandom functions. This would cause an infinite loop, leading to a denial of service DoS...

golang.org/x/text: golang.org/x/text: Denial of Service via invalid UTF-8 input

A flaw was found in golang.org/x/text. The norm.Iter component can enter an infinite loop when processing input that contains invalid UTF-8 Unicode Transformation Format - 8-bit bytes. A remote attacker could exploit this vulnerability by providing specially crafted input, leading to a Denial of...
