Description Robert Frohl 2021-05-27 09:17:03 UTC 
CVE-2021-33574

The mq_notify function in the GNU C Library (aka glibc) through 2.33 has a
use-after-free. It may use the notification thread attributes object (passed
through its struct sigevent parameter) after it has been freed by the caller,
leading to a denial of service (application crash) or possibly unspecified other
impact.
