https://notcve.org/view.php?id=CVE-2021-4157
An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could potentially use this flaw to crash the system or escalate privileges on the system. Se encontró un fallo de escritura fuera de los límites de la memoria (1 o 2 bytes de memoria) en el subsistema NFS del kernel de Linux en la forma en que los usuarios usan el mirroring (replicación de archivos con NFS). Un usuario, que tenga acceso al montaje NFS, podría potencialmente usar este fallo para bloquear el sistema o escalar privilegios en el sistema • https://bugzilla.redhat.com/show_bug.cgi?id=2034342 https://lore.kernel.org/lkml/20210517140244.822185482%40linuxfoundation.org https://security.netapp.com/advisory/ntap-20220602-0007 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-4157 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2022-27666
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 •

https://notcve.org/view.php?id=CVE-2022-0742
Memory leak in icmp6 implementation in Linux Kernel 5.13+ allows a remote attacker to DoS a host by making it go out-of-memory via icmp6 packets of type 130 or 131. We recommend upgrading past commit 2d3916f3189172d5c69d33065c3c21119fe539fc. Una pérdida de memoria en la implementación de icmp6 en el Kernel de Linux versión 5.13+, permite a un atacante remoto hacer DoS a un host haciendo que salga de la memoria por medio de paquetes icmp6 de tipo 130 o 131.
