CVE-2024-25742

A vulnerability was found in AMD SEV-SNP, where a malicious hypervisor can potentially break confidentiality and integrity of SEV-SNP on Linux guests by injecting interrupts. An attacker can inject interrupt 0x80, which is used by Linux for legacy 32-bit system calls, and arbitrarily change the...

SUSE CVE-2024-25743

In the Linux kernel through 6.9, an untrusted hypervisor can inject virtual interrupts 0 and 14 at any point in time and can trigger the SIGFPE signal handler in userspace applications. This affects AMD SEV-SNP and AMD SEV-ES...

DEBIAN-CVE-2024-26813

In the Linux kernel, the following vulnerability has been resolved: vfio/platform: Create persistent IRQ handlers The vfio-platform SETIRQS ioctl currently allows loopback triggering of an interrupt before a signaling eventfd has been configured by the user, which thereby allows a NULL pointer...

Disrupting AMD SEV-SNP on Linux® With Interrupts

AMD ID: AMD-SB-3008 Potential Impact: N/A Severity: N/A Summary Researchers from ETH Zurich have shared with AMD a paper titled “Heckler: Disrupting AMD SEV-SNP with Interrupts.” In their paper, the researchers report that a malicious hypervisor can potentially break confidentiality and integrity...

CVE-2024-26788 dmaengine: fsl-qdma: init irq after reg initialization

In the Linux kernel, the following vulnerability has been resolved: dmaengine: fsl-qdma: init irq after reg initialization Initialize the qDMA irqs after the registers are configured so that interrupts that may have been pending from a primary kernel don't get processed by the irq handler before ...

SUSE CVE-2023-52633

In the Linux kernel, the following vulnerability has been resolved: um: time-travel: fix time corruption In 'basic' time-travel mode without =inf-cpu or =ext, we still get timer interrupts. These can happen at arbitrary points in time, i.e. while in timerread, which pushes time forward just a...

CVE-2024-26765

CVE-2024-26765 concerns the Linux kernel on LoongArch. The issue arises when hotplugging nonboot CPUs: IRQs are disabled before calling init_fn(), intended to silence warnings and avoid interrupts, but this is tied to the rcu_cpu_starting warning path (CPU: 1, pid: 0). The result is a race where ...
