Descriptions
In the Linux kernel, the following vulnerability has been resolved: icmp: Fix a data-race around sysctl_icmp_errors_use_inbound_ifaddr. While reading sysctl_icmp_errors_use_inbound_ifaddr, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its reader.
A flaw was found in the Linux kernel's ICMP protocol. A race condition can occur when reading the sysctl_icmp_errors_use_inbound_ifaddr resource due to a missing lock, potentially impacting system stability and resulting in a denial of service.
