https://notcve.org/view.php?id=CVE-2022-0854
A memory leak flaw was found in the Linux kernel’s DMA subsystem, in the way a user calls DMA_FROM_DEVICE. This flaw allows a local user to read random memory from the kernel space. Se ha encontrado un fallo de pérdida de memoria en el subsistema DMA del kernel de Linux, en la forma en que un usuario llama a DMA_FROM_DEVICE. Este fallo permite a un usuario local leer memoria aleatoria del espacio del kernel • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/kernel/dma/swiotlb.c?h=v5.17-rc8&id=aa6f8dcbab473f3a3c7454b74caa46d36cdc5d13 https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://www.debian.org/security/2022/dsa-5161 https://www.debian.org/security/2022/dsa-5173 https://access.redhat.com/security/cve/CVE-2022-0854 https://bugzilla.redhat.com/show_bug.cgi?id=2058395 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-401: Missing Release of Memory after Effective Lifetime •

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.

https://notcve.org/view.php?id=CVE-2021-4197
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 •
