AI-suggested
A fix has been implemented by adding a CAP_SYS_ADMIN capability check to the __resource_resize_store() function, restricting BAR resize operations to privileged users only. Users should update their Linux kernel to a version that includes this fix once available. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's PCI/sysfs interface allows unprivileged users to resize PCI device BARs via the __resource_resize_store() function without proper capability checks. This could disrupt active device drivers by modifying PCI device configuration. The issue is addressed by adding a CAP_SYS_ADMIN capability check to restrict this operation to privileged users.
