CVE-2020-12656
https://notcve.org/view.php?id=CVE-2020-12656
gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c in the rpcsec_gss_krb5 implementation in the Linux kernel through 5.6.10 lacks certain domain_release calls, leading to a memory leak. Note: This was disputed with the assertion that the issue does not grant any access not already available. It is a problem that on unloading a specific kernel module some memory is leaked, but loading kernel modules is a privileged operation. A user could also write a kernel module to consume any amount of memory they like and load that replicating the effect of this bug ** EN DISPUTA ** En la función gss_mech_free en el archivo net/sunrpc/auth_gss/gss_mech_switch.c en la implementación rpcsec_gss_krb5 en el kernel de Linux versiones hasta 5.6.10 carece de ciertas llamadas domain_release, onllevando a una perdida de memoria. Nota: Esto se discutió con la afirmación de que el tema no otorga ningún acceso no disponible. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html https://bugzilla.kernel.org/show_bug.cgi?id=206651 https://usn.ubuntu.com/4483-1 https://usn.ubuntu.com/4485-1 • CWE-401: Missing Release of Memory after Effective Lifetime •
