Important: kernel

Issue Overview: A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM L0 advertising eIBRS support to L1. An attacker at L...

Amazon Linux 2023 : bpftool, kernel, kernel-devel (ALAS2023-2023-132)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-132 advisory. 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...

SUSE SLED15: xen / xen-devel / xen-doc-html / xen-libs / xen-libs-32bit / etc (SUSE-SU-2023:0692-1)

The remote SUSE Linux SLED15 / SLEDSAP15 / SLES15 / SLESSAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:0692-1 advisory. - CVE-2022-27672: Fixed speculative execution vulnerability due to RAS being dynamically partitioned...

USN-5924-1 linux-azure, linux-azure, linux-azure vulnerabilities

It was discovered that the Upper Level Protocol ULP subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execut...

CVE-2022-27672

A flaw was found in HW. When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch, potentially resulting in information disclosure. Mitigation The current mitigations for spectre V4 or spectrev2 should mitiga...

USN-5883-1: Linux kernel (HWE) vulnerabilities

Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service system crash or execute arbitrary code. CVE-2022-4378 It was discovered that an out-of-bounds write vulnerability existed i...

K43357358: AMD processors vulnerability CVE-2022-23823

Security Advisory Description A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure. CVE-2022-23823 also known as hertzbleed Impact Successful exploitation of this...

SUSE CVE-2012-2934

Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service host hang via sequential execution of instructions across a non-canonical boundary, a different...

SUSE CVE-2016-9377

Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service guest crash by leveraging IDT entry miscalculation...

SUSE CVE-2016-9378

Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service guest crash by leveraging an incorrect choice for software interrupt delivery...

SUSE CVE-2017-5926

Page table walks conducted by the MMU during virtual to physical address translation leave a trace in the last level cache of modern AMD processors. By performing a side-channel attack on the MMU operations, it is possible to leak data and code pointers from JavaScript, breaking ASLR...

SUSE CVE-2021-26318

A timing and power-based side channel attack leveraging the x86 PREFETCH instructions on some AMD CPUs could potentially result in leaked kernel address space information...

SUSE CVE-2022-23825

Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure...

The vulnerability of the System Management Unit (SMU) component of AMD processors allows a hacker to trigger a service failure.

The vulnerability of the System Management Unit SMU component of AMD processors arises from operations that occur outside the buffer in memory. Exploiting this vulnerability can allow a malicious actor to cause service failures remotely...
