Doc Text: |
A flaw was found in the Linux kernel's implementation of Unix sockets. A server polling for client-socket data could put the peer socket on a wait list; the peer socket could then close the connection, making the reference on the wait list no longer valid. This could lead to bypassing the permissions on a Unix socket and packets being injected into the stream, and could also panic the machine (denial of service).
