libxslt libxsltLibxslt: libxml2: heap use-after-free in libxslt caused by atype corruption in xmlattrptr

Input Validation, Double Free, Use After Free, Race Condition
CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:H

A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption.

A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of service or unexpected behavior.
