The Vulners team has released nmap-vulners 2.0

The Vulners team has releasednmap-vulners 2.0. This plugin an NSE script turns the popular Nmap port scanner into a black-box vulnerability scanner. Simply run $ nmap -sV --script vulners to get a prioritized report on vulnerabilities and exploits. And all of this is available for free with no...

CVE-2026-68553

A flaw was found in Coturn. An authenticated TURN user can exploit a format string vulnerability by injecting printf-style format specifiers into the STUN USERNAME or REALM attribute. This can lead to a crash of the coturn process, resulting in a Denial of Service DoS and termination of active TU...

CVE-2026-74576

A flaw was found in the Linux kernel's memory management. This vulnerability allows for unbounded recursion in the slab free path, a process where the kernel manages and releases small blocks of memory. When certain kernel memory allocation caches kmalloc caches form a cycle during internal data...

CVE-2026-74550

A flaw was found in the kernel. When the network stack fails to allocate a peer entry, it can send un-rate-limited Internet Control Message Protocol ICMP or Neighbor Discovery NDISC Redirect messages. This can be exploited by a remote attacker to cause an uncontrolled flood of network traffic,...

SUSE CVE-2026-72194

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: add depth limit to indxfindbuffer to prevent stack overflow indxfindbuffer recursively descends the B+ tree index with no depth limit. A crafted NTFS image with circular index node references causes unbounded recursion,...

SUSE CVE-2026-73566

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.21, node-tar's filesFilter in src/list.ts uses the recursive mapHas helper to walk an archive entry path upward with path.dirname and no segment cap when tar.t... or tar.x... receives a non-empty member-selection list. A...
