https://notcve.org/view.php?id=CVE-2021-3714
23 Aug 2022 — 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 pu... • https://access.redhat.com/security/cve/CVE-2021-3714 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVE-2022-2639 – kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size()
https://notcve.org/view.php?id=CVE-2022-2639
23 Aug 2022 — An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se ha encontrado un error de coerción de enteros en el módulo del kernel openvswitch. Dado un número suficien... • https://github.com/bb33bb/CVE-2022-2639-PipeVersion • CWE-192: Integer Coercion Error CWE-681: Incorrect Conversion between Numeric Types •

CVE-2022-2625 – postgresql: Extension scripts replace objects not belonging to the extension.
https://notcve.org/view.php?id=CVE-2022-2625
18 Aug 2022 — 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.
