VCID-15kx-qz81-87cu Aliases: CVE-2025-49795	A NULL pointer dereference vulnerability was found in libxml2 when processing XPath XML expressions. This flaw allows an attacker to craft a malicious XML input to libxml2, leading to a denial of service.	There are no reported fixed by versions.
VCID-3mkc-h7u6-6beh Aliases: CVE-2025-49796	A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory.	There are no reported fixed by versions.
VCID-6h1b-etzt-juap Aliases: CVE-2025-49794	A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors.	There are no reported fixed by versions.
VCID-9r6n-66y4-3be2 Aliases: CVE-2025-6170	A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.	There are no reported fixed by versions.
