https://notcve.org/view.php?id=CVE-2022-0322
A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). Se ha encontrado un fallo en la función sctp_make_strreset_req en el archivo net/sctp/sm_make_chunk.c en el protocolo de red SCTP en el kernel de Linux con un acceso de privilegio de usuario local. En este fallo, un intento de usar más búfer del asignado desencadena un problema BUG_ON, conllevando a una denegación de servicio (DOS) • https://bugzilla.redhat.com/show_bug.cgi?id=2042822 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a2d859e3fc97e79d907761550dbc03ff1b36479c https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-0322 • CWE-681: Incorrect Conversion between Numeric Types CWE-704: Incorrect Type Conversion or Cast •

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).

CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 1CVE-2022-24778 – Incorrect Authorization in imgcrypt
https://notcve.org/view.php?id=CVE-2022-24778
The imgcrypt library provides API exensions for containerd to support encrypted container images and implements the ctd-decoder command line tool for use by containerd to decrypt encrypted container images. The imgcrypt function `CheckAuthorization` is supposed to check whether the current used is authorized to access an encrypted image and prevent the user from running an image that another user previously decrypted on the same system. In versions prior to 1.1.4, a failure occurs when an image with a ManifestList is used and the architecture of the local host is not the first one in the ManifestList. Only the first architecture in the list was tested, which may not have its layers available locally since it could not be run on the host architecture. Therefore, the verdict on unavailable layers was that the image could be run anticipating that image run failure would occur later due to the layers not being available. • https://github.com/containerd/imgcrypt/commit/6fdd9818a4d8142107b7ecd767d839c9707700d9 https://github.com/containerd/imgcrypt/issues/69 https://github.com/containerd/imgcrypt/releases/tag/v1.1.4 https://github.com/containerd/imgcrypt/security/advisories/GHSA-8v99-48m9-c8pm https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4SJUNSC7YZLA745EMKWK2GKEV57GE52K https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TAHAAOOA3KZJC2I5WHCR3XVBJBNWTWUE https://lists.fe • CWE-303: Incorrect Implementation of Authentication Algorithm CWE-863: Incorrect Authorization •
