CVSS: 10.0EPSS: 1%CPEs: 14EXPL: 0CVE-2019-14896 – kernel: heap-based buffer overflow in lbs_ibss_join_existing function in drivers/net/wireless/marvell/libertas/cfg.c
https://notcve.org/view.php?id=CVE-2019-14896
A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP. Se encontró una vulnerabilidad de desbordamiento de búfer basada en el montón en el kernel de Linux, versión kernel-2.6.32, en el controlador de chip WiFi Marvell. Un atacante remoto podría causar una denegación de servicio (bloqueo del sistema) o, posiblemente, ejecutar código arbitrario, cuando se llama a la función lbs_ibss_join_existing después de que una STA se conecta a un AP. A heap-based buffer overflow vulnerability was found in the Linux kernel's Marvell WiFi chip driver. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html http://packetstormsecurity.com/files/155879/Kernel-Live-Patch-Security-Notice-LSN-0061-1.html http://packetstormsecurity.com/files/156185/Kernel-Live-Patch-Security-Notice-LSN-0062-1.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14896 https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lists.fedoraproject.org/archives/list& • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

__btrfs_free_extent in fs/btrfs/extent-tree.c in the Linux kernel through 5.3.12 calls btrfs_print_leaf in a certain ENOENT case, which allows local users to obtain potentially sensitive information about register values via the dmesg program. NOTE: The BTRFS development team disputes this issues as not being a vulnerability because “1) The kernel provide facilities to restrict access to dmesg - dmesg_restrict=1 sysctl option. So it's really up to the system administrator to judge whether dmesg access shall be disallowed or not. 2) WARN/WARN_ON are widely used macros in the linux kernel. If this CVE is considered valid this would mean there are literally thousands CVE lurking in the kernel - something which clearly is not the case. ** EN DISPUTA ** __btrfs_free_extent en fs / btrfs / extension-tree.c en el kernel de Linux hasta la versión 5.3.12 llama a btrfs_print_leaf en un caso ENOENT determinado, lo que permite a los usuarios locales obtener información potencialmente confidencial sobre los valores de registro a través del programa dmesg. NOTA: El equipo de desarrollo de BTRFS cuestiona estos problemas por no ser una vulnerabilidad porque “1) El núcleo proporciona facilidades para restringir el acceso a la opción dmesg - dmesg_restrict = 1 sysctl. • https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19039 https://lists.debian.org/debian-lts-announce/2020/12/msg00015.html https://usn.ubuntu.com/4414-1 • CWE-532: Insertion of Sensitive Information into Log File •
