In imgsys, there is a possible out of bounds read due to a missing valid range checking. This could lead to local information disclosure with System execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS07326455; Issue ID: ALPS07326409. En imgsys, existe una posible lectura fuera de los límites debido a una falta de comprobación de rango válido. • https://corp.mediatek.com/product-security-bulletin/September-2023 • CWE-125: Out-of-bounds Read •
CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 0CVE-2023-3777 – Use-after-free in Linux kernel's netfilter: nf_tables component
https://notcve.org/view.php?id=CVE-2023-3777
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. Una vulnerabilidad de Use-After-Free en el componente netfilter: nf_tables del kernel de Linux puede explotarse para lograr una escalada de privilegios local. Cuando nf_tables_delrule() vacía las reglas de la tabla, no se verifica si la cadena está vinculada y la regla del propietario de la cadena también puede liberar los objetos en determinadas circunstancias. Recomendamos actualizar al pasado commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. A use-after-free flaw was found in the Linux kernel's netfilter: nf_tables component, which can be exploited to achieve local privilege escalation. • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8 https://kernel.dance/6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8 https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/CVE-2023-3777 https://bugzilla.redhat.com/show_bug.cgi?id=223 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2023-4015 – Use-after-free in Linux kernel's netfilter: nf_tables component
https://notcve.org/view.php?id=CVE-2023-4015
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. On an error when building a nftables rule, deactivating immediate expressions in nft_immediate_deactivate() can lead unbinding the chain and objects be deactivated but later used. We recommend upgrading past commit 0a771f7b266b02d262900c75f1e175c7fe76fec2. Una vulnerabilidad de use-after-free en el netfilter del kernel de Linux: nf_tables componente puede ser explotado para lograr la escalada de privilegios locales. En un error al crear una regla nftables, desactivar expresiones inmediatas en nft_immediate_deactivate() puede llevar a desenlazar la cadena y los objetos se desactiven pero se usen más tarde.
