Created: Apr 12, 2017    Updated: Dec 3, 2018
Resolved Date: Apr 23, 2017
Found In Version: 8.0.0.16
Fix Version: 8.0.0.17
Severity: Standard
Applicable for: Wind River Linux 8
Component/s: Kernel

Description

The ping_unhash function in net/ipv4/ping.c in the Linux kernel through 4.10.8 is too late in obtaining a certain lock and consequently cannot ensure that disconnect function calls are safe, which allows local users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a socket system call.
