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-2023-46836

The CVE pertains to Xen virtualization. The issue is a race condition where mitigations for XSA-422 (Branch Type Confusion) and XSA-434 (Speculative Return Stack Overflow) are not IRQ-safe; one entry path remains with interrupts enabled, and combined with the Meltdown XPTI fix (XSA-254) this was ...
