Exploit availability:
No public exploit available
Vulnerable software:
Linux kernel
Linux kernel
Software vendor:
Linux Foundation
Linux Foundation
Description
The vulnerability allows a local unprivileged attacker to cause DoS condition no the target system.
The weakness exists due to the function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr. A local attacker can induce kernel memory corruption, trigger use-after-free and double free error in network namespaces code to cause the system to crash.
