CVE-2025-7424: Access of Resource Using Incompatible Type ('Type Confusion') in GNOME libxslt
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.
AI Analysis
Technical Summary
The vulnerability in libxslt arises from type confusion involving the xmlNode.psvi field, which is used interchangeably for stylesheet and source nodes. This can cause heap use-after-free and memory corruption during XML processing. The flaw allows attackers to crash applications or cause denial of service. Red Hat advisories RHBA-2025:12345 and RHSA-2026:11015 provide updated libxslt packages that fix this issue in Red Hat Enterprise Linux 10 and Hardened Images RPMs. The CVSS v3.1 score is 7.5 (high), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability (denial of service).
Potential Impact
Exploitation of this vulnerability can cause application crashes or memory corruption, leading to denial of service or unexpected behavior in applications using libxslt for XML transformations. There is no indication of confidentiality or integrity impact. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Red Hat has released official patches addressing CVE-2025-7424 in libxslt packages for Red Hat Enterprise Linux 10 and related products.
