Detailsinfo

A vulnerability classified as critical was found in Linux Kernel 2.6.19.1 (Operating System). Affected by this vulnerability is the function tcp_read_sock. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect availability. The summary by CVE is:

The tcp_read_sock function in net/ipv4/tcp.c in the Linux kernel before 2.6.34 does not properly manage skb consumption, which allows local users to cause a denial of service (system crash) via a crafted splice system call for a TCP socket.

The issue has been introduced in 11/29/2006. The weakness was presented 06/07/2013 (Website). It is possible to read the advisory at github.com. This vulnerability is known as CVE-2013-2128 since 02/19/2013. The exploitation appears to be easy. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 01/03/2022).

The vulnerability was handled as a non-public zero-day exploit for at least 2382 days. During that time the estimated underground price was around $5k-$25k.
