DEBIAN-CVE-2021-47069

In the Linux kernel, the following vulnerability has been resolved: ipc/mqueue, msg, sem: avoid relying on a stack reference past its expiry domqtimedreceive calls wqsleep with a stack local address. The sender domqtimedsend uses this address to later call pipelinedsend. This leads to a very hard...
