AMD Diam-diam Mencantumkan 31 Kerentanan CPU Baru, Mengeluarkan Panduan Patch

January 15, 2023 by Coffee Bean

AMD diam-diam membocorkan 31 kerentanan CPU baru dalam pembaruan januari, mencakup chip Ryzen untuk konsumen dan prosesor pusat data EPYC. Pembaruan kerentananjugamenyertakan daftar versi AGESA, dengan mitigasi untuk prosesor yang terperngaruh. AMD mengungkapkan kerentanan dalam pengungkapan terkoordinasi dengan beberapa peneliti, termasuk tim dari google, Apple dan Oracle.

Seperti yang sering kita lihat pada sistem lama, beberapa mungkin tidak diperbarui. Tampaknya jua beberapa model yang terkena dampak belum memliki mitigasi.

Kerentanan mencakup tiga varian baru untuk PC desktop Ryzen yang ditujukan untuk konsumen, HEDT, Pro, dan prosesor seluler.

kerentanan mencakup chip desktop Pinnacle Ridge seri 2000 Ryzen, bersama dengan produk APU seri 2000 dan 5000 yang hadir dengan grafik terintegrasi (Raven Ridge, Cezanne).

AMD juga telah mendaftarkan 28 kerentanan untuk prosesor EPYC-nya, empat diantaranya sangat parah. Tiga dari varian tingkat keparahan tinggi memungkinkan eksekusi kode arbitrer melalui berbagai vektor serangan, sementara satu varian memungkinkan penulisan data ke wilayah tertentu yang dapat menyebabkan hilangnya integritas dan ketersediaan data. Para peneliti juga menemukan 15 kerentanan lain dengan tingkat keparahan sedang dan sembilan vulnerabilitas tingkat rendah

Chip AMD telah lama dikenal memiliki kerentanan yang diketahui lebih sedikit daripada model intel.

Keberhasilan AMD baru-baru ini dalam merebut pangsa pasar dari Intel, terutama di pasar pusat data yang berfokus pada keamanan, akan membuat para peneliti lebih mengalihkan pandangan mereka ke arsitektur AMD untuk mencari potensi celah keamanan. AMD juga memiliki beberapa pengungkapan kerentanan baru lainnya di masa lalu.
