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-2026-89454

CVE-2026-89454 affects the Linux kernel in the PCI plda driver. The function plda_init_interrupts() initializes IRQ domains and creates IRQ mappings but fails to unwind them when a later step fails. Specifically, if platform_get_irq() or irq_create_mapping() fails, the domains are never deinitial...
