CVSS: 4.7EPSS: 0%CPEs: 12EXPL: 0CVE-2019-18660 – kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure
https://notcve.org/view.php?id=CVE-2019-18660
The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. El kernel de Linux anterior a la versión 5.4.1 en powerpc permite la exposición de información porque la mitigación Spectre-RSB no está implementada para todas las CPU aplicables, también conocido como CID-39e72bf96f58. Esto está relacionado con arch / powerpc / kernel / entry_64.S y arch / powerpc / kernel / security.c. A flaw was found in the way the Linux kernel implemented a software flush of the Count Cache (indirect branch cache) and Link (Return Address) Stack on the PowerPC platform. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/11/27/1 https://access.redhat.com/errata/RHSA-2020:0174 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=39e72bf96f5847ba87cc5bd7a3ce0fed813dc9ad https://lists.fedoraproject.org& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

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 •

In the AppleTalk subsystem in the Linux kernel before 5.1, there is a potential NULL pointer dereference because register_snap_client may return NULL. This will lead to denial of service in net/appletalk/aarp.c and net/appletalk/ddp.c, as demonstrated by unregister_snap_client, aka CID-9804501fa122. En el subsistema AppleTalk en el kernel de Linux versiones anteriores a 5.1, se presenta una posible desreferencia del puntero NULL porque la función register_snap_client puede devolver NULL. Esto conllevará a una denegación de servicio en los archivos net/appletalk/aarp.c y net/appletalk/ddp.c, como es demostrado por la función unregister_snap_client, también se conoce como CID-9804501fa122. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9804501fa1228048857910a6bf23e085aade37cc https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https:/&# • CWE-476: NULL Pointer Dereference •
