A null pointer dereference flaw was found in the nft_inner.c functionality of netfilter in the Linux kernel. This issue could allow a local user to crash the system or escalate their privileges on the system.

Este problema podría permitir que un usuario local bloquee el sistema o aumente sus privilegios en el sistema. • https://access.redhat.com/security/cve/CVE-2023-5972 https://bugzilla.redhat.com/show_bug.cgi?id=2248189 https://github.com/torvalds/linux/commit/505ce0630ad5d31185695f8a29dde8d29f28faa7 https://github.com/torvalds/linux/commit/52177bbf19e6e9398375a148d2e13ed492b40b80 • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-6111 – Use-after-free in Linux kernel's netfilter: nf_tables component
https://notcve.org/view.php?id=CVE-2023-6111
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the argument sync is true, making it possible to free a catchall set element many times. We recommend upgrading past commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630. 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. La función nft_trans_gc_catchall no eliminó el elemento del conjunto general de catchall_list cuando el argumento sync es verdadero, lo que hace posible liberar un elemento del conjunto general muchas veces. Recomendamos actualizar más allá del commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=93995bf4af2c5a99e2a87f0cd5ce547d31eb7630 https://kernel.dance/93995bf4af2c5a99e2a87f0cd5ce547d31eb7630 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3OXWBKK7RTQOGGDLQGCZFS753VLGS2GD https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3S55P23EYAWDHXZPJEVTGIRZZRICYI3Z https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/IG6IF3FUY7LVZJMFRPANAU4L4PSJ3ESQ https://li • CWE-416: Use After Free •
CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2023-39198 – Kernel: qxl: race condition leading to use-after-free in qxl_mode_dumb_create()
https://notcve.org/view.php?id=CVE-2023-39198
A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation. Se encontró una condición de ejecución en el controlador QXL del kernel de Linux. La función qxl_mode_dumb_create() desreferencia el qobj devuelto por qxl_gem_object_create_with_handle(), pero el identificador es el único que contiene una referencia a él. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-39198 https://bugzilla.redhat.com/show_bug.cgi?id=2218332 https://lists.debian.org/debian-lts-announce/2024/06/msg00016.html • CWE-416: Use After Free •
