SUSE CVE-2020-10766

A logic bug flaw was found in Linux kernel before 5.8-rc1 in the implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced...

SUSE CVE-2020-13844

Arm Armv8-A core implementations utilizing speculative execution past unconditional changes in control flow may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka "straight-line speculation."...

SUSE 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...

SUSE CVE-2021-28689

x86: Speculative vulnerabilities with bare non-shim 32-bit PV guests 32-bit x86 PV guest kernels run in ring 1. At the time when Xen was developed, this area of the i386 architecture was rarely used, which is why Xen was able to use it to implement paravirtualisation, Xen's novel approach to...

SUSE CVE-2021-31829

kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can...

SUSE CVE-2021-34556

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack...

SUSE CVE-2021-35477

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled...

SUSE CVE-2022-29900

Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions...

SUSE CVE-2022-29901

Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under...

The vulnerability of the `ib_prctl_set()` function in the Linux operating system’s kernel allows a hacker to gain access to protected information.

The vulnerability of the ibprctlset function in the Linux operating system’s kernel is due to incorrect activation of error protection mechanisms related to speculative execution in processors. Exploiting this vulnerability can allow a remote attacker to gain access to protected information...

x86: Cross-Thread Return Address Predictions

ISSUE DESCRIPTION It has been discovered that on some AMD CPUs, the RAS Return Address Stack, also called RAP - Return Address Predictor - in some AMD documentation, and RSB - Return Stack Buffer - in Intel terminology is dynamically partitioned between non-idle threads. This allows an attacker t...

Cross-Thread Return Address Predictions

Bulletin ID: AMD-SB-1045 Potential Impact: Information Disclosure Summary AMD internally discovered a potential vulnerability where certain AMD processors may speculatively execute instructions at an incorrect return site after an SMT mode switch that may potentially lead to information disclosur...
