CVE-2026-105482

A flaw was found in the Node.js DNS resolver APIs. Hostnames passed to dns.resolve that contain an embedded NUL character can be truncated when processed by c-ares. An attacker who can supply such a name may cause the application to resolve and act on an unintended hostname. Mitigation To mitigat...

CVE-2026-105482

A flaw in Node.js DNS resolution allows hostnames containing a NUL byte to be silently truncated by the dns.resolve functions and dns.reverse. This is an incomplete fix of CVE-2026-48930, which only covered dns.lookup and the net/tls host options. Because the name is passed to c-ares as a C strin...

CVE-2026-105482

A flaw in the Node.js DNS resolution mechanism allows hostnames containing a NUL byte to be silently truncated by the dns.resolve*() functions and dns.reverse(). Because names are passed to c-ares as C strings, an attacker could use a hostname like attacker.example .trusted.example to bypass vali...

CVE-2026-41096-POC

the bug is at DnsQueryRaw function to be specific, inside DnsRawTruncateMessageForUdp so you need a program to call it. I could be wrong, but currently there isnt a service or default program in windows 11 that use this function, thats why i needed client.c. this repo has 2 files, client.c and...

CVE-2026-98955

The Linux kernel contains a vulnerability in the __skb_flow_dissect() function where key_control->thoff is computed using min_t(u16, ...). This causes a u16 truncation of skb->len; if skb->len modulo 65536 is smaller than nhoff, thoff is set to a bogus small value . This can lead callers...

CVE-2026-98950

The Linux kernel contains a vulnerability in the bpf_flow_dissect() function where the hlen (header length) parameter can undergo u16 truncation during offset sanitization. When hlen exceeds 65535, the upper bound is truncated before being used in clamp_t(u16, ..., hlen) . For example, if hlen is...
