NVD Description

Note: Versions mentioned in the description apply only to the upstream tigervnc-license package and not the tigervnc-license package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later.
