hw: cpu: intel: Intra-Mode BTI

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...

kernel: speculation on incompletely validated data on IBM Power9

A flaw was found in the Linux kernel. IBM Power9 processors can speculatively operate on data stored in the L1 cache before it has been completely validated. The attack has limited access to memory and is only able to access memory normally permissible to the execution context. The highest threat...

hw: cpu: LFENCE/JMP Mitigation Update for CVE-2017-5715

A flaw was found in hw. The speculative execution window of AMD LFENCE/JMP mitigation MITIGATION V2-2 may be large enough to be exploited on AMD CPUs...

Amazon Linux 2 : kernel (ALAS-2022-1793)

The version of kernel installed on the remote host is prior to 4.14.276-211.499. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1793 advisory. 2024-02-01: CVE-2022-41858 was added to this advisory. A use-after-free flaw was found in the Linux kernel's FUSE...

Amazon Linux 2 : kernel (ALASKERNEL-5.4-2022-013)

The version of kernel installed on the remote host is prior to 5.4.50-25.83. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-013 advisory. A logic bug flaw was found in the Linux kernel's implementation of SSBD. A bug in the logic handling allows a...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A flaw in the Linux kernel's X86 CPU Power management options functionality was found, related to the speculative execution behavior kind of attacks. This issue arises when a user...

Vulnerability fixed in ARM, AMD and Intel processors

Researchers at VU Amsterdam have found a new variant of the Spectre vulnerability. The researchers have dubbed the attack Branch History Injection. Previous mitigation for Spectre v2 is not sufficient to fully fix the vulnerability, according to the researchers. According to the researchers, this...

New Exploit Bypasses Existing Spectre-V2 Mitigations in Intel, AMD, Arm CPUs

Researchers have disclosed a new technique that could be used to circumvent existing hardware mitigations in modern processors from Intel, AMD, and Arm, and stage speculative execution attacks such as Spectre to leak sensitive information from host memory. Attacks like Spectre are designed to bre...

CVE-2021-26401

A flaw was found in hw. The speculative execution window of AMD LFENCE/JMP mitigation MITIGATION V2-2 may be large enough to be exploited on AMD CPUs. Mitigation AMD recommends mitigation that uses generic retpoline...

PT-2022-9728 · Amd +4 · Amd Cpus +4

Name of the Vulnerable Software and Affected Versions: AMD CPUs affected versions not specified Description: The issue is related to speculative execution in AMD CPUs, which may allow data leakage by transiently executing beyond unconditional direct branches. This could potentially lead to the...
