Descriptions

The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag.

El kernel de Linux versiones anteriores a 5.17.2, maneja inapropiadamente los permisos de seccomp. La ruta de código PTRACE_SEIZE permite a atacantes omitir las restricciones previstas al establecer el flag PT_SUSPEND_SECCOMP

A flaw was found in the Linux kernel. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag, possibly disabling seccomp.

Linux suffers from two seccomp bugs with a PT_SUSPEND_SECCOMP permission bypass and ptracer death race condition.
