Name of the Vulnerable Software and Affected Versions Intel and AMD microprocessors affected versions not specified AMD microprocessor families 15h through 18h Description The issue is related to mis-trained branch predictions for return instructions, which may allow arbitrary speculative code...

PT-2022-3604

Name of the Vulnerable Software and Affected Versions Intel microprocessor generations 6 through 8 Description The issue is related to errors in processing the ret instruction, which retrieves an address for transition from the stack. This can allow an attacker to disclose protected information...

M1 Chip Vulnerability

This is a new vulnerability against Apples M1 chip. Researchers say that it is unpatchable. Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory, however, have created a novel hardware attack, which combines memory corruption and speculative execution attacks to sidestep...

Don’t panic! “Unpatchable” Mac vulnerability discovered

Researchers at MITs Computer Science & Artificial Intelligence Lab CSAIL found an attack surface in a hardware-level security mechanism utilized in Apple M1 chips. The flaw is unpatchable, but attackers would need to chain it with other vulnerabilities to make use of the attack method. The hardwa...

MIT Researchers Discover New Flaw in Apple M1 CPUs That Can't Be Patched

A novel hardware attack dubbed PACMAN has been demonstrated against Apple's M1 processor chipsets, potentially arming a malicious actor with the capability to gain arbitrary code execution on macOS systems. It leverages "speculative execution attacks to bypass an important memory protection...

Amazon Linux AMI : kernel (ALAS-2022-1591)

The version of kernel installed on the remote host is prior to 4.14.281-144.502. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2022-1591 advisory. A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMAFROMDEVICE. This flaw...

CVE-2021-26400

AMD processors may speculatively re-order load instructions which can result in stale data being observed when multiple processors are operating on shared memory, resulting in potential data leakage...

CVE-2021-26400

AMD processors may speculatively re-order load instructions which can result in stale data being observed when multiple processors are operating on shared memory, resulting in potential data leakage...

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...

PT-2022-6506 · Linux +6 · Linux Kernel +6

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...
