CVE-2026-60080——
———Use After Free vulnerability in the Rust deserialization logic of Apache Fory. This issue affects Apache Fory from 0.13.0 through 1.3.0.
A crafted Fory payload could cause undefined behavior, process crash, or potential memory disclosure.
Users are recommended to upgrade to version 1.4.0, which fixes the issue.3hCVE-2026-637296.6 MED—
———The SyncTeX parser (synctex_parser.c) shipped with TeX Live and embedded by downstream consumers such as GNOME Evince contains a heap use-after-free vulnerability that allows attackers to crash applications or potentially execute arbitrary code by supplying a malformed .synctex or .synctex.gz file. A malformed SyncTeX file can construct a ref node with a NULL parent pointer, causing the replacement routine to fail to detach the node from its sibling chain, which triggers recursive freeing of live tree nodes and leaves dangling pointers that are later accessed by the parser during document load.43mCVE-2026-159057.8 ALT—
