GHSA-WH7Q-2HGQ-2XJ7

Vulnerability from github – Published: 2023-06-28 21:30 – Updated: 2024-04-04 05:16

Details

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.

Severity ?

4.7 (Medium)
