CVE-2026-6298 is a critical heap buffer overflow vulnerability in Skia, the 2D graphics library used by Google Chrome and Chromium. The flaw affects Google Chrome versions prior to 147.0.7727.101 on Linux and prior to 147.0.7727.101/102 on Windows and macOS. A remote attacker can trigger the vulnerability by causing the target to process a crafted HTML page that exercises the vulnerable Skia code path. The memory corruption condition can result in out-of-bounds writes within heap-allocated memory during graphics-related processing, creating a path to information disclosure and potentially more severe memory-corruption outcomes depending on exploit reliability and surrounding process constraints.
