Ubuntu 20.04 LTS : Linux kernel (Intel IOTG) vulnerabilities (USN-5362-1)
The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5362-1 advisory. Nick Gregory discovered that the Linux kernel incorrectly handled network offload functionality. A local attacker could use this to cause a denial of...

CVE-2022-0001
CVE-2022-0001 pertains to Intel CPUs and Branch History Injection (BHI). The issue arises from non-transparent sharing of branch predictor selectors between contexts, potentially allowing an authorized local attacker to disclose information via speculative execution side channels. Affected materi...
CVE-2022-0002
A flaw was found in hw. The Intra-mode BTI refers to a variant of Branch Target Injection aka SpectreV2 BTI where an indirect branch speculates to an aliased predictor entry for a different indirect branch in the same predictor mode, and a disclosure gadget at the predicted target transiently...
CVE-2022-0001
A flaw was found in hw. The Branch History Injection BHI describes a specific form of intra-mode BTI. This flaw allows an unprivileged attacker to manipulate the branch history before transitioning to supervisor or VMX root mode. This issue is an effort to cause an indirect branch predictor to...

AMD CPUs 安全漏洞
AMD CPUs is a GPU component from AMD Corporation. A security vulnerability exists in AMD CPUs that stems from an attacker being able to bypass access restrictions to AMD processor data via the branch predictor selector lfence/jmp to read sensitive information...
Important: kernel
Issue Overview: AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on AMD instances 5a. This is done by default, and no administrator action is...
