You should update your Samsung phone ASAP - this zero-day flaw just got patched
Android users are at risk, so install the security update as soon as it lands on your handset.
The security flaw, issued a critical base score of 8.8 by Samsung Mobile (a CNA), is described as an "out-of-bounds write in libimagecodec.quram.so prior to SMR Sep-2025 Release 1 allows remote attackers to execute arbitrary code." Samsung's urgent release, following WhatsApp's private disclosure of the active exploit, builds upon Apple's mitigation of a similar vulnerability, tracked as CVE-2025-43300, which is described as a memory corruption issue that occurs when malicious image files are processed. In a security advisory in August, WhatsApp noted active attacks and said that it resolved a separate flaw impacting the messaging service that "could have allowed an unrelated user to trigger processing of content from an arbitrary URL on a target's device."
