Description

A flaw was found in the Linux kernel, specifically within its IPv4 Internet Control Message Protocol (ICMP) component. This vulnerability occurs because the system does not properly check the type of ICMP replies before attempting to process them. An attacker could potentially exploit this by sending specially crafted extended echo replies, which might cause the system to access memory outside of its intended boundaries. This could lead to system instability, such as a crash, or potentially expose sensitive information.
