Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.10.8
Description
The issue is related to the
ping unhash function in the Linux kernel, specifically in the net/ipv4/ping.c file. It is associated with inadequate access control. The exploitation of this issue can allow a local attacker to cause a denial of service by utilizing access to the IPPROTO ICMP protocol value in a socket system call. This can lead to a system panic.Recommendations
For Linux kernel versions prior to 4.10.8, update to version 4.10.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the
IPPROTO ICMP protocol value in socket system calls to minimize the risk of exploitation.Exploit
