CVSS: 5.5EPSS: 0%CPEs: 7EXPL: 0CVE-2023-6622 – Kernel: null pointer dereference vulnerability in nft_dynset_init()
https://notcve.org/view.php?id=CVE-2023-6622
A null pointer dereference vulnerability was found in nft_dynset_init() in net/netfilter/nft_dynset.c in nf_tables in the Linux kernel. This issue may allow a local attacker with CAP_NET_ADMIN user privilege to trigger a denial of service. Se encontró una vulnerabilidad de desreferencia de puntero nulo en nft_dynset_init() en net/netfilter/nft_dynset.c en nf_tables en el kernel de Linux. Este problema puede permitir que un atacante local con privilegios de usuario CAP_NET_ADMIN active una denegación de servicio. • 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-2023-6622 https://bugzilla.redhat.com/show_bug.cgi?id=2253632 https://github.com/torvalds/linux/commit/3701cd390fd731ee7ae8b8006246c8db82c72bea https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/AAOVK2F3ALGKYIQ5IOMAYEC2DGI7BWAW https://lists.fedoraproject.org/archives/list/package-announce& • CWE-476: NULL Pointer Dereference •
CVSS: 4.9EPSS: 0%CPEs: 2EXPL: 0CVE-2023-34324 – Possible deadlock in Linux kernel event handling
https://notcve.org/view.php?id=CVE-2023-34324
Closing of an event channel in the Linux kernel can result in a deadlock. This happens when the close is being performed in parallel to an unrelated Xen console action and the handling of a Xen console interrupt in an unprivileged guest. The closing of an event channel is e.g. triggered by removal of a paravirtual device on the other side. As this action will cause console messages to be issued on the other side quite often, the chance of triggering the deadlock is not neglectable. Note that 32-bit Arm-guests are not affected, as the 32-bit Linux kernel on Arm doesn't use queued-RW-locks, which are required to trigger the issue (on Arm32 a waiting writer doesn't block further readers to get the lock). El cierre de un canal de eventos en el kernel de Linux puede provocar un punto muerto. Esto sucede cuando el cierre se realiza en paralelo a una acción de la consola Xen no relacionada y al manejo de una interrupción de la consola Xen en un invitado sin privilegios. El cierre de un canal de eventos se desencadena, por ejemplo, al retirar un dispositivo paravirtual del otro lado. • https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://lists.debian.org/debian-lts-announce/2024/01/msg00005.html https://xenbits.xenproject.org/xsa/advisory-441.html • CWE-400: Uncontrolled Resource Consumption •
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 •
