A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. Se ha encontrado un fallo de lectura de uso de memoria previamente liberada en la función sock_getsockopt() en el archivo net/core/sock.c debido a la carrera de SO_PEERCRED y SO_PEERGROUPS con listen() (y connect()) en el kernel de Linux.

A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. Se ha encontrado un fallo de desbordamiento del búfer de la pila en el código de transformación de IPsec ESP en net/ipv4/esp4.c y net/ipv6/esp6.c. Este fallo permite a un atacante local con un privilegio de usuario normal sobrescribir los objetos de la pila del núcleo y puede causar una amenaza de escalada de privilegios local • https://github.com/plummm/CVE-2022-27666 https://bugzilla.redhat.com/show_bug.cgi?id=2061633 https://github.com/torvalds/linux/commit/ebe48d368e97d007bfeb76fcb065d6cfc4c96645 https://security.netapp.com/advisory/ntap-20220429-0001 https://www.debian.org/security/2022/dsa-5127 https://www.debian.org/security/2022/dsa-5173 https://access.redhat.com/security/cve/CVE-2022-27666 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. Se encontró un fallo de escritura no privilegiado en el manejador de archivos en el subsistema de grupos de control y espacios de nombres del kernel de Linux en la forma en que los usuarios presentan acceso a algunos procesos menos privilegiados que son controlados por cgroups y presentan procesos padres con mayores privilegios. En realidad se trata de las versiones cgroup2 y cgroup1 de los grupos de control. • https://bugzilla.redhat.com/show_bug.cgi?id=2035652 https://lore.kernel.org/lkml/20211209214707.805617-1-tj%40kernel.org/T https://security.netapp.com/advisory/ntap-20220602-0006 https://www.debian.org/security/2022/dsa-5127 https://www.debian.org/security/2022/dsa-5173 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-4197 • CWE-287: Improper Authentication •
