While Google did not go into deep technical detail in its security advisory, the company did acknowledge that an exploit for the high-severity CVE (CVE-2026-85046) currently exists in the wild. Salvatore Gulizia is credited with reporting this flaw and was awarded a $1,000 bounty for the responsible disclosure.

In his own write-up, Gulizia goes into much more detail on what this CVE entails. Found and reported in early August, it is essentially a V8 bug in the compilers that causes an array containing PACKED_ELEMENTS to receive the map PACKED_SMI_ELEMENTS.

This can be turned into an arbitrary read/write on the JavaScript heap.
