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.
En librt en la Biblioteca C de GNU (también se conoce como glibc) versiones hasta 2.34, el archivo sysdeps/unix/sysv/linux/mq_notify.c, maneja inapropiadamente determinados datos NOTIFY_REMOVED, conllevando una desreferencia de puntero NULL. NOTA: esta vulnerabilidad se introdujo como efecto secundario de la corrección de CVE-2021-33574
