CVE-2026-53025

A flaw was found in the Linux kernel's Greybus raw subsystem. A local user application could trigger a use-after-free vulnerability by disconnecting a Greybus raw bundle while its associated character device was still open. When the application subsequently attempts to release the character devic...

SUSE CVE-2026-53025

In the Linux kernel, the following vulnerability has been resolved: greybus: raw: fix use-after-free on cdev close This addresses a use-after-free bug when a raw bundle is disconnected but its chardev is still opened by an application. When the application releases the cdev, it causes the followi...
