Description

A flaw was found in the Linux kernel's rpmsg core. A race condition exists between the driver_override_show() and driver_override_store() functions. This allows the driver_override string to be freed while it is still being read, leading to a use-after-free vulnerability. This could potentially result in system instability or a denial of service.

Statement

Red Hat acknowledges the upstream Linux kernel correction for «rpmsg» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.
