CISA orders feds to patch Samsung zero-day used in spyware attacks www.bleepingcomputer.com/news/secu…
CISA ordered U.S. federal agencies today to patch a critical Samsung vulnerability that has been exploited in zero-day attacks to deploy LandFall spyware on devices running WhatsApp.
Tracked as CVE-2025-21042, this out-of-bounds write security flaw was discovered in Samsung’s libimagecodec.quram.so library, allowing remote attackers to gain code execution on devices running Android 13 and later.
While Samsung patched it in April following a report from Meta and WhatsApp Security Teams, Palo Alto Networks' Unit 42 revealed last week that attackers had been exploiting it since at least July 2024 to deploy previously unknown LandFall spyware via malicious DNG images sent over WhatsApp.
