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. Esto ocurre porque las ramas condicionales pueden superar el límite de 128 KB de la arquitectura MIPS • http://www.openwall.com/lists/oss-security/2021/09/15/5 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.14.10 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=37cb28ec7d3a36a5bace7063a3dba633ab110f8b https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://security.netapp.com/advisory/ntap-20211008-0003 https://www.debian.org/security/2022/dsa-5096 •
