CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 0CVE-2023-5633 – Kernel: vmwgfx: reference count issue leads to use-after-free in surface handling
https://notcve.org/view.php?id=CVE-2023-5633
The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a use-after-free flaw in the way memory objects were handled when they were being used to store a surface. When running inside a VMware guest with 3D acceleration enabled, a local, unprivileged user could potentially use this flaw to escalate their privileges. Los cambios en el recuento de referencias realizados como parte de las correcciones CVE-2023-33951 y CVE-2023-33952 expusieron una falla de use-after-free en la forma en que se manejaban los objetos de memoria cuando se usaban para almacenar una superficie. Cuando se ejecuta dentro de un invitado de VMware con la aceleración 3D habilitada, un usuario local sin privilegios podría utilizar esta falla para aumentar sus privilegios. • https://access.redhat.com/errata/RHSA-2024:0113 https://access.redhat.com/errata/RHSA-2024:0134 https://access.redhat.com/errata/RHSA-2024:0461 https://access.redhat.com/errata/RHSA-2024:1404 https://access.redhat.com/errata/RHSA-2024:4823 https://access.redhat.com/errata/RHSA-2024:4831 https://access.redhat.com/security/cve/CVE-2023-5633 https://bugzilla.redhat.com/show_bug.cgi?id=2245663 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-42752
An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating `skb_shared_info` in the userspace, which is exploitable in systems without SMAP protection since `skb_shared_info` contains references to function pointers. Se encontró una falla de desbordamiento de enteros en el kernel de Linux. Este problema lleva a que el kernel asigne `skb_shared_info` en el espacio de usuario, lo cual es explotable en sistemas sin protección SMAP ya que `skb_shared_info` contiene referencias a punteros de función. • http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://access.redhat.com/security/cve/CVE-2023-42752 https://bugzilla.redhat.com/show_bug.cgi?id=2239828 https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=915d975b2ffa https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=c3b704d4a4a2 • CWE-190: Integer Overflow or Wraparound •

A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.
