Описание
In the Linux kernel, the following vulnerability has been resolved:
icmp: Fix data-races around sysctl.
While reading icmp sysctl variables, they can be changed concurrently.
So, we need to add READ_ONCE() to avoid data-races.
A flaw was found in the Linux kernel's ICMP protocol. A race condition can occur when reading the ICMP sysctl variables due to a missing lock, potentially impacting system stability and resulting in a denial of service.
Отчет
