Description

A flaw was found in the Linux kernel's net/rose component. A local user can trigger a NULL pointer dereference by calling connect() a second time while a connection attempt is already in progress. This improper handling of concurrent connection attempts can lead to a system crash, resulting in a Denial of Service (DoS).

Mitigation

No mitigation is specified in collected source.
