What is CVE-2026-68106?
A division-by-zero vulnerability in the Linux kernel's amdgpu driver occurs when invalid UVD dimensions (width/height <16) cause `fs_in_mb` to become zero. This can lead to a crash when calculating `num_dpb_buffer`; affected users should apply the kernel update.
Azərbaycanca: Linux kernel-in amdgpu sürücüsündə UVD ölçüləri etibarsız olduqda (width/height <16) yaranan sıfıra bölmə zəifliyidir. Bu, `num_dpb_buffer` hesablanarkən sistemin çökməsinə səbəb ola bilər; təsirə məruz qalan istifadəçilər kernel yeniləməsini tətbiq etməlidir.
