https://notcve.org/view.php?id=CVE-2021-38300
arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context. This occurs because conditional branches can exceed the 128 KB limit of the MIPS architecture. arch/mips/net/bpf_jit.c en el kernel de Linux anterior a la versión 5.4.10 puede generar código máquina no deseado al transformar programas cBPF sin privilegios, permitiendo la ejecución de código arbitrario dentro del contexto del kernel.

CVE-2021-40690 – Bypass of the secureValidation property
https://notcve.org/view.php?id=CVE-2021-40690
All versions of Apache Santuario - XML Security for Java prior to 2.2.3 and 2.1.7 are vulnerable to an issue where the "secureValidation" property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. This allows an attacker to abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.
