Description

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because a queued bridge packet can retain a freed bridge master in its skb->dev field until it is reinjected. When the packet is later reinjected, the system attempts to use the freed bridge master, leading to a use-after-free condition. This can result in system instability or a denial of service.
