CVSS: 10.0EPSS: 2%CPEs: 13EXPL: 0CVE-2019-14901 – kernel: heap overflow in marvell/mwifiex/tdls.c
https://notcve.org/view.php?id=CVE-2019-14901
A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.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://access.redhat.com/errata/RHSA-2020:0204 https://access.redhat.com/errata/RHSA-2020:0328 https://access.redhat.com/errata/RHSA-2020:0339 https://access.redhat.com/errata/RHSA-2020:0374 https://access.redhat.com/errata/RHSA- • CWE-122: Heap-based Buffer Overflow CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •

A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA. Se encontró un desbordamiento de búfer en la región stack de la memoria en el kernel de Linux, versión kernel-2.6.32, en el controlador del chip WiFi de Marvell. Un atacante es capaz de causar una denegación de servicio (bloqueo del sistema) o, posiblemente, ejecutar código arbitrario, cuando una STA funciona en modo IBSS (permite conectar estaciones juntas sin el uso de un AP) y se conecta a otra STA. • 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-2019-14897 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-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code. Se detectó un desbordamiento de búfer en la región heap de la memoria en el kernel de Linux, todas las versiones 3.x.x y versiones 4.x.x anteriores a 4.18.0, en el controlador del chip WiFi de Marvell. El fallo podría presentarse cuando la estación intenta una negociación de conexión durante el manejo de la configuración country de dispositivos remotos. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.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://access.redhat.com/errata/RHSA-2020:0328 https://access.redhat.com/errata/RHSA-2020:0339 https://access.redhat.com/errata/RHSA-2020:0374 https://access.redhat.com/errata/RHSA-2020:0375 https://access.redhat.com/errata/RHSA- • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

In the Linux kernel 5.3.11, mounting a crafted btrfs image twice can cause an rwsem_down_write_slowpath use-after-free because (in rwsem_can_spin_on_owner in kernel/locking/rwsem.c) rwsem_owner_flags returns an already freed pointer, En el kernel de Linux versión 5.3.11, montar una imagen btrfs especialmente diseñada dos veces puede causar un uso de la memoria previamente liberada de la función rwsem_down_write_slowpath porque (en la función rwsem_can_spin_on_owner en el archivo kernel/locking/rwsem.c) la función rwsem_owner_flags devuelve un puntero ya liberado. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19318 https://lists.debian.org/debian-lts-announce/2021/03/msg00010.html https://security.netapp.com/advisory/ntap-20200103-0001 https://usn.ubuntu.com/4414-1 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 1CVE-2019-19319 – kernel: out-of-bounds write in ext4_xattr_set_entry in fs/ext4/xattr.c
https://notcve.org/view.php?id=CVE-2019-19319
In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call, aka CID-345c0dbf3a30. En el kernel de Linux anterior a la versión 5.2, una operación setxattr, posterior al montaje de una imagen ext4 especialmente diseñada, puede causar un acceso de escritura fuera de límites debido a un uso de la memoria previamente liberada de la función ext4_xattr_set_entry en el archivo fs/ext4/xattr.c cuando se usa un valor grande de old_size en una llamada memset también conocido como CID-345c0dbf3a30. An out-of-bounds write flaw was found in the Linux kernel’s Ext4 FileSystem in the way it uses a crafted ext4 image. This flaw allows a local user with physical access to crash the system or potentially escalate their privileges on the system. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://bugzilla.suse.com/show_bug.cgi?id=1158021 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=345c0dbf3a30 https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19319 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https&# • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
