In the Linux kernel, the following vulnerability has been resolved:
PCI/sysfs: Add CAP_SYS_ADMIN check to __resource_resize_store()
Currently, the __resource_resize_store() allows writing to the resourceN_resize sysfs attribute to change a BAR's size without checking for capabilities, currently relying only on the file access check.
Resizing a BAR modifies PCI device configuration and can disrupt active drivers. After the upcoming conversion to static attributes, it will also trigger resource file updates via sysfs_update_groups().
Add a CAP_SYS_ADMIN check to prevent unprivileged users from performing BAR resize operations.
