Details
A type confusion vulnerability exists in the JavaScript engine of Foxit Software’s Foxit PDF Reader, version 10.1.0.37527. A specially crafted PDF document can trigger an improper use of an object, resulting in memory corruption and arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability.

Details
A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits - a096ccca6e50 ("tun: tun_chr_open(): correctly initialize socket uid"), - 66b2c338adce ("tap: tap_open(): correctly initialize socket uid"), pass "inode->i_uid" to sock_init_data_uid() as the last parameter and that turns out to not be accurate.

GHSA-9F23-58RV-2HX4
Vulnerability from github – Published: 2025-10-14 06:31 – Updated: 2026-04-27 21:30
VLAI
Details
A flaw was found in the exsltFuncResultComp() function of libxslt, which handles EXSLT 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.

"details": "A flaw was found in the exsltFuncResultComp() function of libxslt, which handles EXSLT \u003cfunc:result\u003e 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.",
