CVE-2023-45322 is fixed in 7 products on 1 platform, first by DEBIAN-CVE-2023-45322, released October 6, 2023. It is not reported as exploited. Patch Radar priority: Routine.
libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails. This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is "I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail."
