Overview

Affected versions of this package are vulnerable to Use After Free in the xive_smp_probe process. An attacker can cause heap corruption, information disclosure, or kernel panic by triggering a failure in irq_domain_alloc_irqs during early SMP initialization, leading to dereferencing of a freed pointer. This is only exploitable if the system experiences an allocation failure in irq_domain_alloc_irqs during the SMP probe phase, which cannot be induced on demand.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
