Linux Distros Unpatched Vulnerability : CVE-2026-89455

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - PCI: plda: Fix use-after-free of event IRQs during teardown pldapcieirqdomaindeinit removes pcie-eventdomain via irqdomainremove, but the per-event IRQs mapped...

CVE-2026-89454

A flaw was found in the Linux kernel's PCI PLDA driver. This vulnerability occurs in the pldainitinterrupts function, where Interrupt Request IRQ domains are not properly deinitialized if certain initialization steps fail. A local attacker could potentially exploit this resource leak, leading to...

CVE-2026-89455

A flaw was found in the Linux kernel's PCI PLDA driver. During the teardown of Interrupt Request IRQ domains, the system can attempt to access memory that has already been freed. This 'use-after-free' vulnerability occurs because the domain's internal data is released before all associated IRQs a...

CVE-2026-89455

CVE-2026-89455 is a use-after-free vulnerability in the Linux kernel's PCI PLDA driver . During device teardown, irq_domain_remove() frees the event IRQ domain's internal data before the deferred free_irq() calls (managed by devres) execute, causing a later dereference of the already-freed domain...
