https://notcve.org/view.php?id=CVE-2021-4204
An out-of-bounds (OOB) memory access flaw was found in the Linux kernel's eBPF due to an Improper Input Validation. This flaw allows a local attacker with a special privilege to crash the system or leak internal information. Se ha encontrado un fallo de acceso a memoria fuera de límites (OOB) en el eBPF del kernel de Linux debido a una comprobación de entrada inapropiada. Este fallo permite a un atacante local con un privilegio especial bloquear el sistema o filtrar información interna. • https://github.com/tr3ee/CVE-2021-4204 https://access.redhat.com/security/cve/CVE-2021-4204 https://bugzilla.redhat.com/show_bug.cgi?id=2039178 https://security-tracker.debian.org/tracker/CVE-2021-4204 https://security.netapp.com/advisory/ntap-20221228-0003 https://www.openwall.com/lists/oss-security/2022/01/11/4 • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

An out-of-bounds memory access flaw was found in the Linux kernel Intel’s iSMT SMBus host controller driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input data. This flaw allows a local user to crash the system.

CVSS: 8.0EPSS: 0%CPEs: 12EXPL: 0CVE-2022-2625 – postgresql: Extension scripts replace objects not belonging to the extension.
https://notcve.org/view.php?id=CVE-2022-2625
A vulnerability was found in PostgreSQL. This attack requires permission to create non-temporary objects in at least one schema, the ability to lure or wait for an administrator to create or update an affected extension in that schema, and the ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF NOT EXISTS. Given all three prerequisites, this flaw allows an attacker to run arbitrary code as the victim role, which may be a superuser. Se ha encontrado una vulnerabilidad en PostgreSQL. Este ataque requiere permiso para crear objetos no temporales en al menos un esquema, la capacidad de atraer o esperar que un administrador cree o actualice una extensión afectada en ese esquema, y la capacidad de atraer o esperar que una víctima utilice el objeto objetivo en CREATE OR REPLACE o CREATE IF NOT EXISTS. • https://bugzilla.redhat.com/show_bug.cgi?id=2113825 https://security.gentoo.org/glsa/202211-04 https://www.postgresql.org/about/news/postgresql-145-138-1212-1117-1022-and-15-beta-3-released-2496 https://access.redhat.com/security/cve/CVE-2022-2625 • CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
