Описание
A flaw was found in the netrom module in the Linux kernel. A race condition can occur when reading the sysctl_netrom_transport_no_activity_timeout resource due to a missing lock, which may impact system stability and can result in a denial of service.
Отчет
The netrom module is not built in the kernel shipped in Red Hat Enterprise Linux 8 and 9, so it is not affected by this vulnerability.
