TITLE

GNU C Library Resource Management Error Vulnerability

DESCRIPTION

The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 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. The vulnerability stems from the library's mq_notify function having a use-after-free feature.
