Detailsinfo

A vulnerability was found in Linux Kernel 3.10.34/3.12.15/3.13.7 (Operating System). It has been rated as critical. This issue affects the function inet_frag_intern of the file net/ipv4/inet_fragment.c of the component ICMP Handler. The manipulation as part of a ICMP Echo Request leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is availability. The summary by CVE is:

Race condition in the inet_frag_intern function in net/ipv4/inet_fragment.c in the Linux kernel through 3.13.6 allows remote attackers to cause a denial of service (use-after-free error) or possibly have unspecified other impact via a large series of fragmented ICMP Echo Request packets to a system with a heavy CPU load.
