https://notcve.org/view.php?id=CVE-2021-3714
A flaw was found in the Linux kernels memory deduplication mechanism. Previous work has shown that memory deduplication can be attacked via a local exploitation mechanism. The same technique can be used if an attacker can upload page sized files and detect the change in access time from a networked service to determine if the page has been merged. Se ha encontrado un fallo en el mecanismo de de duplicación de memoria del kernel de Linux. Trabajos anteriores han demostrado que la de duplicación de memoria puede ser atacada por medio de un mecanismo de explotación local. • https://access.redhat.com/security/cve/CVE-2021-3714 https://arxiv.org/abs/2111.08553 https://arxiv.org/pdf/2111.08553.pdf https://bugzilla.redhat.com/show_bug.cgi?id=1931327 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2021-3659
A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability. Se ha encontrado un fallo de desreferencia de puntero NULL en el subsistema de red inalámbrica IEEE versión 802.15.4 del kernel de Linux en la forma en que el usuario cierra la conexión LR-WPAN. Este fallo permite a un usuario local bloquear el sistema. • https://access.redhat.com/security/cve/CVE-2021-3659 https://bugzilla.redhat.com/show_bug.cgi?id=1975949 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1165affd484889d4986cf3b724318935a0b120d8 • CWE-252: Unchecked Return Value CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2022-2873
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. Se ha encontrado un fallo de acceso a memoria fuera de límites en el controlador de host iSMT SMBus del kernel de Linux, en la forma en que un usuario desencadena I2C_SMBUS_BLOCK_DATA (con el ioctl I2C_SMBUS) con datos de entrada maliciosos.

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') •
