CVE-2022-48727

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Avoid consuming a stale esr value when SError occur When any exception other than an IRQ occurs, the CPU updates the ESREL2 register with the exception syndrome. An SError may also become pending, and will be...

Linux kernel security vulnerabilities

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 the Linux kernel that stems from the use of a deprecated esr value when a SError occurs in the KVM:arm64 module...

CVE-2021-47229

CVE-2021-47229 concerns the Linux kernel PCI aardvark driver. A kernel panic could occur when a new PIO transfer is started before the previous one finished; the kernel will issue an External Abort/SSeror interrupt leading to a reboot. The root cause analysis noted a previously added Trusted Firm...

CVE-2024-35995

A vulnerability was found in the ACPI subsystem's CPPC driver in the Linux kernel. This issue occurs due to the mishandling of memory access bit width during performance capability calculations, which can lead to misaligned memory accesses and cause kernel panics on affected platforms...

CVE-2024-35995

In the Linux kernel, the following vulnerability has been resolved: ACPI: CPPC: Use accesswidth over bitwidth for system memory accesses To align with ACPI 6.3+, since bitwidth can be any 8-bit value, it cannot be depended on to be always on a clean 8b boundary. This was uncovered on the Cobalt 1...

CVE-2024-35995

CVE-2024-35995 describes a Linux kernel issue where the ACPI CPPC code misread system memory by relying on bit_width, risking incorrect memory access. The fix switches to using access_width for size calculation and reads/writes using an offset and width, with a fallback to bit_width if access_wid...

GSD-2022-1000580 KVM: arm64: Avoid consuming a stale esr value when SError occur

KVM: arm64: Avoid consuming a stale esr value when SError occur This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v5.15.22 by commit...

ARM guests may induce host asynchronous abort

ISSUE DESCRIPTION Depending on how the hardware and firmware have been integrated, guest-triggered asynchronous aborts SError on ARMv8 may be received by the hypervisor. The current action is to crash the host. A guest might trigger an asynchronous abort when accessing memory mapped hardware in a...
