CVE-2025-11731: Access of Resource Using Incompatible Type ('Type Confusion')
A flaw was found in the exsltFuncResultComp() function of libxslt, which handles EXSLT <func:result> elements during stylesheet parsing. Due to improper type handling, the function may treat an XML document node as a regular XML element node, resulting in a type confusion. This can cause unexpected memory reads and potential crashes. While difficult to exploit, the flaw could lead to application instability or denial of service.
AI Analysis
Technical Summary
The vulnerability CVE-2025-11731 involves a type confusion flaw in the exsltFuncResultComp() function of libxslt, which processes EXSLT <func:result> elements. Improper type handling can cause the function to treat an XML document node as a regular XML element node, leading to unexpected memory reads and potential application instability or crashes. The CVSS score is 3.1 (low severity), reflecting the limited impact and difficulty of exploitation. Red Hat Enterprise Linux 10 is affected. Vendor advisories have been published but do not confirm the availability of a patch.
Potential Impact
The impact of this vulnerability is limited to potential application instability or denial of service due to unexpected memory reads caused by type confusion.
