Description

Use-after-free vulnerability in the nfqnl_zcopy function in net/netfilter/nfnetlink_queue_core.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation. NOTE: the affected code was moved to the skb_zerocopy function in net/core/skbuff.c before the vulnerability was announced.

Techniques & Countermeasures

  • CWE-416•Use After Free

    The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
