18-Year-Old Linux SCTP Flaw Could Let Local Users Gain Root and Escape Containers
Brief
A use-after-free bug in Linux's SCTP networking code can be turned into full root on a host, and Tencent researchers say they used it to escape a container and reach the machine underneath.
The flaw has existed since 2008. The fix already shipped: stable kernels 7.
- 6, 6.
- 42, 6.
- 101 and 6.
- 148, released August 3, close it. Anyone running an older kernel with SCTP reachable should update.
