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-2026-89722

A flaw was found in the Linux kernel's PCI/sysfs component. A local user with root privileges could trigger an out-of-bounds read in the pciwritelegacyio function by writing to the legacyio sysfs file with a size less than four bytes. This improper handling of the write buffer can lead to memory...
