https://notcve.org/view.php?id=CVE-2023-39189
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. Se encontró una falla en el subsistema Netfilter en el kernel de Linux. La función nfnl_osf_add_callback no validó el campo opt_num controlado por el modo de usuario. • 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-2023-39189 https://bugzilla.redhat.com/show_bug.cgi?id=2226777 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2023-42754
A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system. Se encontró una falla de desreferencia del puntero NULL en la pila ipv4 del kernel de Linux. Se suponía que el búfer de socket (skb) estaba asociado con un dispositivo antes de llamar a __ip_options_compile, lo que no siempre es el caso si ipvs redirige el skb. • 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-2023-42754 https://bugzilla.redhat.com/show_bug.cgi?id=2239845 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GISYSL3F6WIEVGHJGLC2MFNTUXHPTKQH https://lists.fedoraproject.org/archives/list/package-announc • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2023-5345 – Use-after-free in Linux kernel's fs/smb/client component
https://notcve.org/view.php?id=CVE-2023-5345
A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve local privilege escalation. In case of an error in smb3_fs_context_parse_param, ctx->password was freed but the field was not set to NULL which could lead to double free. We recommend upgrading past commit e6e43b8aa7cd3c3af686caf0c2e11819a886d705. Se puede explotar una vulnerabilidad de use-after-free en el componente fs/smb/client del kernel de Linux para lograr una escalada de privilegios local. En caso de un error en smb3_fs_context_parse_param, se liberó ctx->password pero el campo no se configuró en NULL, lo que podría provocar una doble liberación. Recomendamos actualizar al commit anterior e6e43b8aa7cd3c3af686caf0c2e11819a886d705. A flaw was found in the SMB client component in the Linux kernel. • http://packetstormsecurity.com/files/177029/Kernel-Live-Patch-Security-Notice-LSN-0100-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e6e43b8aa7cd3c3af686caf0c2e11819a886d705 https://kernel.dance/e6e43b8aa7cd3c3af686caf0c2e11819a886d705 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GISYSL3F6WIEVGHJGLC2MFNTUXHPTKQH https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GPMICQ2HVZO5UAM5KPXHAZKA2U3ZDOO6 https://lists.fedoraproject.org&#x • CWE-416: Use After Free •

A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an information disclosure.
