CVE-2026-42944 HIGH PATCH This Week

Heap overflow denial-of-service in NLnet Labs Unbound recursive DNS resolver versions 1.14.0 through 1.25.0 allows remote unauthenticated attackers to crash the resolver by sending DNS queries containing multiple NSID, DNS Cookie, and/or EDNS Padding options. The flaw stems from a numeric truncation in EDNS field size calculation that lets attacker-influenced data overflow the response buffer. No public exploit identified at time of analysis and not listed in CISA KEV, but the impact is service-wide DNS outage for any user of an affected resolver.

CVE-2026-44927 LOW PATCH Monitor

Pointer difference truncation to signed int in uriparser before version 1.0.2 allows local attackers to cause integer overflow and data integrity issues through specially crafted URI inputs. The vulnerability stems from unsafe casting of pointer arithmetic results (afterLast - first) to int, which can overflow on systems where pointer differences exceed INT_MAX, leading to buffer overflows, incorrect memory calculations, and potential information disclosure. While CVSS score is low (2.9) due to local attack vector and high complexity, the fix adds comprehensive overflow detection using SIZE_MAX checks, indicating real risk in applications processing untrusted URIs locally.

CVE-2026-42371 MEDIUM PATCH This Month

uriparser before 1.0.1 suffers a numeric truncation vulnerability in text range comparison that causes denial of service when processing URIs with gigabyte-scale lengths. The flaw occurs because internal range comparisons truncate large numeric values, allowing maliciously crafted oversized URIs to bypass length validation and trigger memory exhaustion or processing failures. Local attackers can exploit this via specially constructed input, though practical exploitation requires an application to accept and process URIs of exceptional size.

CVE-2025-6965 HIGH POC PATCH CISA This Week

Memory corruption in SQLite versions before 3.50.2 allows network-based attackers with low privileges to manipulate aggregate queries causing integrity impacts. The vulnerability stems from improper validation of aggregate terms against available columns (CWE-197), leading to buffer overflow conditions. CVSS 7.2 (High) with network attack vector but high complexity and partial attack complexity requirements. Vendor-released patch available in SQLite 3.50.2. No confirmed active exploitation (not in CISA KEV), though multiple security advisories from Siemens and OSS-security mailing lists indicate broad downstream impact across industrial control systems and embedded products using SQLite.
