Summary
Multiple integer overflows in Opera 11.60 and earlier allow remote attackers to cause a denial of service (application crash) via a large integer argument to the (1) Int32Array, (2) Float32Array, (3) Float64Array, (4) Uint32Array, (5) Int16Array, or (6) ArrayBuffer function. NOTE: the vendor reportedly characterizes this as "a stability issue, not a security issue."
Exploit prediction
1.14% chance of exploitation in the next 30 days, higher than 66% of all scored CVEs (FIRST EPSS, 2026-11-09).
