CVE-2024-53196

CVE-2024-53196 affects the Linux kernel (arm64/KVM). The issue is that KVM could retire an aborted MMIO instruction and advance the PC even when a synchronous external abort was pending, triggering a kernel WARN in kvm_emulate.h and related call paths. The documented fix is to skip MMIO emulation...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel, which stems from a null pointer dereference in the PCI:endpoint:epf-mhi module when DT is missing mmio...

DEBIAN-CVE-2024-45818

The hypervisor contains code to accelerate VGA memory accesses for HVM guests, when the virtual VGA is in "standard" mode. Locking involved there has an unusual discipline, leaving a lock acquired past the return from the function that acquired it. This behavior results in a problem when emulatin...
