Insufficient validation in ASP BIOS and DRTM commands may allow malicious supervisor x86 software to disclose the contents of sensitive memory which may result in information disclosure. Zafiyet ile ilgili Genel Bilgi, Etki ve Çözümleri için Devamını Oku Kaynak: National Vulnerability Database
In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure to flush the TLB may cause the microcode to use stale TLB translations which may allow for disclosure of SEV guest…
Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage. Zafiyet ile ilgili Genel Bilgi, Etki ve Çözümleri için Devamını Oku Kaynak: National Vulnerability Database
A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code includes a specific x86 instruction sequence that would not be generated by compilers. Zafiyet ile ilgili Genel Bilgi,…
