Veeam ONE Receives Security Update Addressing Critical Vulnerabilities Including CVE-2026-65641
Veeam Software has issued updates for its backup environment monitoring tool Veeam ONE to resolve multiple security vulnerabilities, including issues rated as critical.
The company published a security advisory on 25 August 2026 detailing the fixes for the 13.x branch. Among the addressed flaws is CVE-2026-65641, which permits a service account to perform SMB authentication. This vulnerability received a CVSSv4.0 base score of 9.3 and is rated Critical.
The fixes are delivered in Veeam ONE 13.1 Patch 0 (13.1.0.7233) and Veeam ONE 13.0.2 Patch 1 (13.0.2.7159). The latter release also incorporates vulnerabilities previously corrected in 13.1.0.7034, including CVE-2026-64633 that carries a maximum CVSS score of 10.0.
Veeam initially reported six vulnerabilities resolved in 13.1.0.7034 but later added CVE-2026-64632, bringing the total to seven. All seven issues are now included in the 13.0.2 Patch 1 release.
For users remaining on the 12.x branch, the company released Veeam ONE 12.3 Patch 1 (12.3.0.7165). This update backports fixes for CVE-2026-58074, CVE-2026-64631, and CVE-2026-64632 that were originally addressed in the 13.1.0.7034 release.

Apple iOS Security Architecture: From Power Button to App Launch in Modern Devices
The article examines the complete boot and trust chain in modern iPhones, starting from the immutable BootROM and progressing through iBoot, the XNU kernel, and the Secure Enclave. It explains how Secure Boot verifies signatures but does not guarantee absence of vulnerabilities, allowing exploits like checkm8 to persist across devices. The piece details data protection classes, BFU versus AFU states, and how passcodes interact with hardware-bound keys to limit brute-force attempts. It further describes application sandboxing, entitlements, code signing, and Pointer Authentication (PAC) as layered defenses that raise the cost of exploitation. The analysis shows why modern jailbreaks require multi-stage chains involving kernel read/write, sandbox escapes, and PAC bypasses rather than single vulnerabilities. Overall, the architecture transforms privilege from a simple scalar into a graph of capabilities across isolated components.
Critical PHP Vulnerabilities CVE-2026-109618 and CVE-2026-109619 Enable Unauthenticated Remote Code Execution
Two critical vulnerabilities in PHP, tracked as CVE-2026-109618 and CVE-2026-109619, both scoring CVSS 9.2, were disclosed on October 21. The flaws allow attackers to execute arbitrary code without authentication by triggering out-of-memory conditions that lead to use-after-free memory corruption. Exploitation involves specially crafted requests that manipulate uninitialized arrays and function pointers, with full chains demonstrated via PHP_SESSION_UPLOAD_PROGRESS and fatal error backtraces. The issues affect PHP versions starting from 5.4 and were discovered using AI tools Gemini 4 Argon and GPT-5.6 Sol, resulting in a patch exceeding 10,000 lines of code. Amazon detected attacks as early as October 17, with Cloudflare later reporting millions of exploitation attempts. Mitigation requires updating to patched versions such as PHP 8.2.35, 8.3.36, 8.4.27 or 8.5.12, while temporary workarounds include disabling session upload progress and fatal error backtraces.
Trend Micro ZDI Reports on Critical Linux KSMBD Vulnerabilities Leak to Public Mailing Lists Before Patches
Trend Micro Zero Day Initiative inadvertently published detailed vulnerability reports for the Linux kernel's KSMBD component into public mailing lists. Two flaws received CVSS scores of 9.0, enabling remote code execution under specific conditions. One issue involves a race condition during parallel SMB request handling, while the second stems from an incorrect buffer size calculation in the SMB Direct mechanism that requires RDMA and a writable share. Technical details including root causes and reproduction steps became publicly archived before fixes reached end users. The KSMBD maintainer has already merged a patch for ZDI-CAN-33774 into their repository, yet distribution kernels may still lack the update. Additional privilege-escalation and information-disclosure risks in other kernel components were also described in the leaked messages.
Node.js Issues Security Releases for 26.x, 24.x and 22.x Fixing High-Severity TLS and Brotli Flaws
Node.js published security updates on October 21, 2026 for the 26.x, 24.x and 22.x release lines. The patches address multiple high-severity vulnerabilities affecting TLS hostname validation and the Brotli decoder, along with updates to critical dependencies including OpenSSL and Undici. Several CVEs cover bypasses in certificate hostname checks when IP addresses use full-width digits or when hosts resolve loosely to IP addresses. A particularly serious out-of-bounds write in the Brotli decoder (CVE-2026-111497) could enable remote code execution on services processing compressed responses. Additional fixes resolve keep-alive socket timing issues, DNS resolution truncation with NUL characters, and entropy caching problems in crypto.randomUUID and randomInt functions. The releases also update c-ares, Undici, OpenSSL, SQLite and ca-cert bundles following the eMudhra intermediate CA compromise.
