An update of the glibc package has been released.

  • In librt in the GNU C Library (aka glibc) through 2.34, sysdeps/unix/sysv/linux/mq_notify.c mishandles certain NOTIFY_REMOVED data, leading to a NULL pointer dereference. NOTE: this vulnerability was introduced as a side effect of the CVE-2021-33574 fix. (CVE-2021-38604)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
