https://notcve.org/view.php?id=CVE-2021-3764
A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd() function that allows an attacker to cause a denial of service. The vulnerability is similar to the older CVE-2019-18808. The highest threat from this vulnerability is to system availability. Se ha encontrado un fallo de pérdida de memoria en la función ccp_run_aes_gcm_cmd() del kernel de Linux que permite a un atacante causar una denegación de servicio. La vulnerabilidad es similar a la anterior CVE-2019-18808. • https://access.redhat.com/security/cve/CVE-2021-3764 https://bugzilla.redhat.com/show_bug.cgi?id=1997467 https://github.com/torvalds/linux/commit/505d9dcb0f7ddf9d075e729523a33d38642ae680 https://security-tracker.debian.org/tracker/CVE-2021-3764 • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-4037 – kernel: security regression for CVE-2018-13405
https://notcve.org/view.php?id=CVE-2021-4037
A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS. Se ha encontrado una vulnerabilidad en la lógica de la función fs/inode.c:inode_init_owner() del kernel de LInux que permite a usuarios locales crear archivos para el sistema de archivos XFS con una propiedad de grupo no deseada y con los bits de permiso de ejecución de grupo y SGID establecidos, en un escenario en el que un directorio es SGID y pertenece a un determinado grupo y es escribible por un usuario que no es miembro de este grupo. Esto puede conllevar a una concesión de excesivos permisos cuando no deberían concederse. • https://access.redhat.com/security/cve/CVE-2021-4037 https://bugzilla.redhat.com/show_bug.cgi?id=2004810 https://bugzilla.redhat.com/show_bug.cgi?id=2027239 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=01ea173e103e https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0fa3ecd87848 https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://www.debian.org/security/2022/dsa-5257 • CWE-284: Improper Access Control •
