CVE-2022-49883
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: smm: number of GPRs in the SMRAM image depends on the image format On 64 bit host, if the guest doesn't have X86FEATURELM, KVM will access 16 gprs to 32-bit smram image, causing out-ouf-bound ram access. On 32 bit host,...

CVE-2022-49883
CVE-2022-49883 is a Linux kernel KVM x86 vulnerability related to SMM handling. The issue arises because the number of general purpose registers (GPRs) used for the SMRAM image depends on the image format. On 64‑bit hosts, if the guest lacks X86_FEATURE_LM, KVM may access 16 GPRs for a 32‑bit SMR...
