As we hit mid-October 2025, Samsung has rolled out its monthly security update, patching a total of 33 vulnerabilities across Galaxy devices. This includes 13 high-severity fixes from Google’s Android Security Bulletin and 20 Samsung-specific issues (SVEs), with five rated high severity. For software QA professionals, this patch cycle is a stark reminder of the ongoing battle against mobile threats, especially in a fragmented ecosystem where devices like the Galaxy S24 and S25 series are prime targets.
Key highlights from the update include several privilege escalations and information disclosures that could compromise user data. For instance, SVE-2025-1526 (CVE-2025-21048) involves a relative path traversal in Knox Enterprise, allowing local attackers to execute arbitrary code – a classic flaw stemming from inadequate input validation. Similarly, out-of-bounds read/write bugs in components like libimagecodec.quram.so (SVE-2025-1845, CVE-2025-21055) enable remote attackers to access memory, potentially leading to data leaks or crashes. Google’s contributions address framework and kernel issues, such as CVE-2025-22420 and others, which could affect the Android core on Exynos-powered Samsung phones.
From a QA standpoint, these bugs underscore the challenges of testing across device variants, OS versions (Android 13 through 16), and custom features like Samsung DeX or Knox. Fragmentation means patches roll out unevenly and carrier delays can leave users exposed for weeks. To mitigate this in testing iBeta utilizes fuzzing for boundary errors, rigorous access control testing in multi-user scenarios, and maintaining a stable of physical devices and OS versions to ensure coverage.
