CVE-2024-31076

In the Linux kernel, the following vulnerability has been resolved: genirq/cpuhotplug, x86/vector: Prevent vector leak during CPU offline The absence of IRQDMOVEPCNTXT prevents immediate effectiveness of interrupt affinity reconfiguration via procfs. Instead, the change is deferred until the next...

CVE-2024-31076

CVE-2024-31076: Linux kernel CPU hotplug vector leak in genirq/cpuhotplug (x86/vector). Root cause: when interrupt affinity is reconfigured via procfs, old APIC vectors aren’t reclaimed if the old CPU goes offline before the next trigger on the new CPU, leaving apicd->prev_vector in vector_mat...
