CVE-2026-123592 Hickory DNS 0.26.0-beta.1 before 0.26.2 DNSSEC Validation Bypass via Name Hash Collision

The hickory-net crate in Hickory DNS 0.26.0-beta.1 before 0.26.2 allows DNSSEC validation bypass because Name's Hash ignores label lengths and ValidationCacheKey compares only that hash. An attacker controlling an unsigned delegation whose name differs from a signed target only in dot positions c...

CVE-2026-123592

The hickory-net crate in Hickory DNS versions 0.26.0-beta.1 before 0.26.2 is vulnerable to a DNSSEC validation bypass via a name hash collision. The root cause is that Name's Hash ignores label lengths while ValidationCacheKey compares only that hash. This allows an attacker controlling an unsign...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2026-53221)

In the Linux kernel, the following vulnerability has been resolved: ip6vti: fix incorrect tunnel matching in vti6tnllookup In vti6tnllookup, when an exact match for a tunnel fails, the code falls back to searching for wildcard tunnels: - Tunnels matching the packet's local address, with any remot...

Astra Linux – vulnerability in jq

jq is a command-line JSON processor. Prior to commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq utilized MurmurHash3 with a hard-coded, publicly visible seed 0x432A9843 for all JSON object hash table operations. This allowed attackers to precompute key collisions offline. By providing a special...

In the Linux kernel, the following vulnerability has been resolved: sched: schcake: fix bulk flow accounting logic for host fairness In schcake, we keep track of the count of active bulk flows per host, when running in dst/src host fairness mode, which is used as the round-robin weight when...

CVE-2026-97468

A flaw was found in Apache CXF. The Security Token Service STS and token validation components cache validated security tokens using a weak, non-cryptographic hash function and treat cache matches as proof of validity. A remote attacker can craft a security token that generates a hash collision...

Improper Authentication

Overview org.apache.cxf:cxf-rt-ws-security is a services framework that helps you build and develop services using frontend programming APIs, like JAX-WS and JAX-RS. Affected versions of this package are vulnerable to Improper Authentication due to the STSTokenValidator token-validation cache in...

CVE-2026-97468
