What is CVE-2026-16768?
CVE-2026-16768 is a vulnerability in the gdk-pixbuf library where parsing a specially crafted ICO file with pixel values exceeding the defined palette range leads to an out-of-bounds read due to improper bounds checking. This causes heap bytes to be interpreted as valid palette data, potentially exposing sensitive information. Users should apply updates and avoid opening untrusted ICO files.
Azərbaycanca: CVE-2026-16768 gdk-pixbuf kitabxanasında xüsusi hazırlanmış ICO fayllarının işlənməsi zamanı yaranan boşluqdur. Əgər piksel dəyərləri palitranın hüdudlarını aşarsa, düzgün yoxlama olmadığı üçün heap-dən kənar oxuma (out-of-bounds read) baş verir. Bu, heap məlumatlarının palitra kimi interpretasiyasına səbəb olur; istifadəçilərə təsirlənən komponenti yeniləmək və şübhəli ICO fayllarından ehtiyat etmək tövsiyə olunur.
