CVE-2021-3609 – kernel: race condition in net/can/bcm.c leads to local privilege escalation
https://notcve.org/view.php?id=CVE-2021-3609
.A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.

CVE-2020-10711 – Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic
https://notcve.org/view.php?id=CVE-2020-10711
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10711 https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4411-1 https://usn.ubuntu.com/4412-1 https://usn.ubuntu.com/4413-1 https://usn.ubuntu.com/4414-1 https://usn.ubuntu& • CWE-476: NULL Pointer Dereference •
CVE-2019-14846 – ansible: secrets disclosed on logs when no_log enabled
https://notcve.org/view.php?id=CVE-2019-14846
In Ansible, all Ansible Engine versions up to ansible-engine 2.8.5, ansible-engine 2.7.13, ansible-engine 2.6.19, were logging at the DEBUG level which lead to a disclosure of credentials if a plugin used a library that logged credentials at the DEBUG level. This flaw does not affect Ansible modules, as those are executed in a separate process. En Ansible, todas las versiones de Ansible Engine hasta ansible-engine 2.8.5, ansible-engine 2.7.13, ansible-engine 2.6.19, se registraban en el nivel DEBUG, lo que conlleva a la divulgación de credenciales si un plugin usó una biblioteca que registraba credenciales en el nivel DEBUG. Este defecto no afecta a los módulos de Ansible, ya que son ejecutados en un proceso separado.

Se presenta un desbordamiento del búfer en la región heap de la memoria en el kernel, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A vulnerability was found in the Linux kernel's Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This flaw affects the network interface at the most basic level meaning the attacker only needs to affiliate with the same network device as the vulnerable system to create an attack path. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0204 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
