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: 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 •

https://notcve.org/view.php?id=CVE-2023-5090
A flaw was found in KVM. An improper check in svm_set_x2apic_msr_interception() may allow direct access to host x2apic msrs when the guest resets its apic, potentially leading to a denial of service condition.

https://notcve.org/view.php?id=CVE-2023-1194
An out-of-bounds (OOB) memory read flaw was found in parse_lease_state in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command with a malformed payload to KSMBD, due to a missing check of `NameOffset` in the `parse_lease_state()` function, the `create_context` object can access invalid memory. Se encontró una falla de lectura de memoria Out-Of-Bounds (OOB) en parse_lease_state en la implementación KSMBD del servidor samba en el kernel y CIFS en el kernel de Linux.
