CVE-2022-3566: Linux Kernel TCP tcp_setsockopt race condition

Published Oct 6, 2022
·
Updated

A vulnerability was found in the tcp subsystem in the Linux Kernel, due to a data race around icsk->icskafops. This issue could allow an attacker to leak internal kernel information.

Other sources

A vulnerability was identified in Linux Kernel up to 4.19.316/5.4.278/5.10.220/5.15.161. This impacts the function tcpgetsockopt/tcpsetsockopt of the component TCP Handler. Such manipulation leads to race condition. A high complexity level is associated with this attack. The exploitability is said to be difficult. The vulnerability was introduced in 2.6.12, commit 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 ("Linux-2.6.12-rc2"). Upgrading to version 4.19.317, 5.4.279, 5.10.221, 5.15.162 and 6.1 will fix this issue. The name of the patch is fcd31dd8291b23d713245947ec2b2d99ef07aef2/3b32f265805a49071e2c4568a524398ba22bf93c/d529193eae979a7bf2255cd9fe68b7af7a1c91b3/5bb642cc3355ffd3c8bca0a8bd8e6e65bcc2091c/f49cd2f4d6170d27a2c61f1fecb03d8a70c91f57. The affected component should be upgraded.

The manipulation leads to race condition. It is recommended to apply a patch to fix this issue. The identifier VDB-211089 was assigned to this vulnerability.

setsockopt(IPV6ADDRFORM) and tcpv6connect() change icsk->icskafops under locksock(), but tcp(get|set)sockopt() read it locklessly causes data-race in tcpsetsockopt / tcpv6connect
