🔒 Apple released emergency updates to patch two zero-day WebKit vulnerabilities — CVE-2025-43529 (use-after-free) and CVE-2025-14174 (memory corruption) — that were exploited in an 'extremely sophisticated' attack against targeted individuals. Both bugs affect devices running WebKit on iPhone and iPad and were discovered by Google’s Threat Analysis Group and Apple. Apple fixed the issues across iOS, iPadOS, macOS, tvOS, watchOS, visionOS and Safari and urges users to install updates promptly.

🛡️ CISA warns of multiple memory-corruption vulnerabilities in AzeoTech DAQFactory (release 20.7 and prior) that can be triggered by specially crafted .ctl files. The flaws include out-of-bounds read/write, heap and stack overflows, use-after-free, type confusion, and access of uninitialized pointers; several have CVSS v4 scores up to 8.4. DAQFactory 21.1 addresses these issues and AzeoTech advises avoiding untrusted documents, restricting .ctl file permissions, and using Safe Mode when loading unverified files.

🔒 CISA has added two vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog: CVE-2025-6218 (WinRAR path traversal) and CVE-2025-62221 (Microsoft Windows use-after-free). The agency cited evidence of active exploitation and emphasized that these flaws are frequent attack vectors posing significant risk to the federal enterprise. CISA reiterated that BOD 22-01 requires FCEB agencies to remediate cataloged CVEs by the required due dates and urged all organizations to prioritize timely remediation.

🔒 Google’s AI agent Big Sleep reported five vulnerabilities in Apple’s WebKit used by Safari, including a buffer overflow, two memory-corruption issues, an unspecified crash flaw, and a use-after-free (CVE-2025-43429 through CVE-2025-43434). Apple issued patches across iOS 26.1, iPadOS 26.1, macOS Tahoe 26.1, tvOS 26.1, watchOS 26.1, visionOS 26.1 and Safari 26.1. Users are advised to install the updates promptly to mitigate crash and memory-corruption risks.

⚠️ Redis disclosed a maximum-severity vulnerability, CVE-2025-49844 (RediShell), a use-after-free bug in its Lua scripting implementation that has been assigned a CVSS score of 10.0. An authenticated user can submit crafted Lua scripts to manipulate the garbage collector, trigger a use-after-free, and potentially achieve remote code execution on the host. The issue affects all Redis versions with Lua and was fixed in 6.2.20, 7.2.11, 7.4.6, 8.0.4, and 8.2.2 (released Oct 3, 2025). Administrators should immediately restrict EVAL/EVALSHA via ACLs, avoid exposing Redis instances to the internet, enforce strong authentication, and apply the patches without delay.
