amd: Return Address Predictor vulnerability leading to information disclosure

A side channel vulnerability was found in hw amd. Some AMD CPUs may allow an attacker to influence the return address prediction. This issue may result in speculative execution at an attacker-controlled instruction pointer register, potentially leading to information disclosure...

F5 Networks BIG-IP : Side-channel processor vulnerability (K35135935)

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K35135935 advisory. - Systems with microprocessors utilizing speculative execution may allow unauthorized disclosure of information to an...

x86/AMD: Speculative Return Stack Overflow

ISSUE DESCRIPTION Researchers from ETH Zurich have extended their prior research XSA-422, Branch Type Confusion, a.k.a Retbleed and have discovered INCEPTION, also know as RAS Return Address Stack Poisoning, and Speculative Return Stack Overflow. The RAS is updated when a CALL instruction is...

kernel: KVM: nVMX: missing IBPB when exiting from nested guest can lead to Spectre v2 attacks

A flaw was found in the KVM's Intel nested virtualization feature nVMX. Since L1 and L2 shared branch prediction modes guest-user and guest-kernel, KVM did not protect indirect branches in L1 from steering by a malicious agent in L2. This could allow a malicious nested guest to carry out Spectre ...

USN-5975-1 linux-azure vulnerabilities

Updated on 2023-04-11: Please note that when USN 5975-1 was originally published, it incorrectly included the linux-gcp kernel for Ubuntu 16.04 ESM. References to that kernel have been removed from this USN and the correct information for it has been published in USN 6007-1. Original advisory...

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...

OESA-2023-1157 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: There is a logic error in iouring's implementation which can be used to trigger a use-after-free vulnerability leading to privilege escalation. In the ioprepasyncwork function the assumption that the last iograbidentity call cann...

libde265 代码问题漏洞

Libde265 is a German h.265 video codec. A security vulnerability exists in libde265 version v1.0.10, which stems from a NULL pointer dereference issue found in the ffhevcputunweightedpred8sse method of the sse-motion.cc file...

The vulnerability of AMD’s SMT processor technology, which allows a hacker to disclose protected information

The vulnerability of AMD’s SMT processor technology is related to errors that occur after the processor’s core exits the C0 sleep state. Exploiting this vulnerability can allow an attacker to disclose protected information i.e., gain access to the RAP Return Address Predictor...

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