OESA-2023-1036 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: An out-of-bounds memory access flaw was found in the Linux kernel Intel’s iSMT SMBus host controller driver in the way a user triggers the I2CSMBUSBLOCKDATA with the ioctl I2CSMBUS with malicious input data. This flaw allows a...

CVE-2022-2196

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 ...

AZL-12951 CVE-2022-2196 affecting package kernel for versions less than 5.15.102.1-1

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 L2 with code...

CVE-2022-2196

The CVE-2022-2196 entry concerns a regression in Linux kernel KVM/nVMX where speculative execution could leak from an L2 guest to the host L1 due to inadequate Spectre v2 mitigations (retpolines/IBPB/eIBRS context). The description states an L2 attacker with code execution can influence indirect ...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. The Linux kernel suffers from a security vulnerability that stems from nVMX allowing speculative execution attacks where L2 can execute a Spectre v2 attack against L1 because L1 believes it does not...
