CVE-2023-3439 (published 2023-06-28T00:00:00)
A flaw was found in the MCTP protocol in the Linux kernel. The function mctp_unregister() reclaims the device's relevant resource when a netcard detaches. However, a running routine may be unaware of this and cause the use-after-free of the mdev->addrs object, potentially leading to a denial of service.
Affected products: Vendor: n/a
Product: Linux Kernel (mctp)
