CVE-2021-46961

CVE-2021-46961 involves the Linux kernel where handling of spurious interrupts in the GICv3 IRQ path could trigger a nested NMI and a BUG_ON(in_nmi()), causing a kernel panic. The root cause is enabling IRQs while processing spurious interrups; a rewrite of the commit moved spurious interrupt han...

CVE-2021-46916

A NULL pointer dereference flaw was found in ethtool loopback test in the Linux Kernel. This issue occurs due to a missing qvector associated with the test ring when it is setup, as interrupts are not normally added to the test rings. Exploiting the vulnerability can result in system crash and...

DEBIAN-CVE-2021-46918

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: clear MSIX permission entry on shutdown Add disabling/clearing of MSIX permission entries on device shutdown to mirror the enabling of the MSIX entries on probe. Current code left the MSIX enabled and the pasid...

CVE-2024-25744

A flaw was found in the Linux kernel. A VMM can inject external interrupts on any arbitrary vector at any time, which may allow the guest OS to be manipulated from the VMM side. Mitigation This vulnerability can be mitigated by disabling 32-bit emulation by default for TDX and SEV. The user can...

UBUNTU-CVE-2023-46836

The fixes for XSA-422 Branch Type Confusion and XSA-434 Speculative Return Stack Overflow are not IRQ-safe. It was believed that the mitigations always operated in contexts with IRQs disabled. However, the original XSA-254 fix for Meltdown XPTI deliberately left interrupts enabled on two entry...
