CVSS: 8.3EPSS: 0%CPEs: 5EXPL: 1CVE-2019-9500 – Broadcom brcmfmac driver is vulnerable to a heap buffer overflow
https://notcve.org/view.php?id=CVE-2019-9500
The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer overflow. If the Wake-up on Wireless LAN functionality is configured, a malicious event frame can be constructed to trigger an heap buffer overflow in the brcmf_wowl_nd_results function. This vulnerability can be exploited with compromised chipsets to compromise the host, or when used in combination with CVE-2019-9503, can be used remotely. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions. • https://blog.quarkslab.com/reverse-engineering-broadcom-wireless-chipsets.html https://git.kernel.org/linus/1b5e2423164b3670e8bc9174e4762d297990deff https://kb.cert.org/vuls/id/166939 https://access.redhat.com/security/cve/CVE-2019-9500 https://bugzilla.redhat.com/show_bug.cgi?id=1701224 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 5.5EPSS: 0%CPEs: 32EXPL: 0CVE-2019-11833 – kernel: fs/ext4/extents.c leads to information disclosure
https://notcve.org/view.php?id=CVE-2019-11833
fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem. fs / ext4 / extents.c en el kernel de Linux hasta 5.1.2 no pone a cero la región de memoria no utilizada en el bloque del árbol de extensión, lo que podría permitir a los usuarios locales obtener información confidencial al leer datos no inicializados en el sistema de archivos. A flaw was found in the Linux kernel's implementation of ext4 extent management. The kernel doesn't correctly initialize memory regions in the extent tree block which may be exported to a local user to obtain sensitive information by reading empty/uninitialized data from the filesystem. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://www.securityfocus.com/bid/108372 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource •
CVSS: 6.8EPSS: 0%CPEs: 30EXPL: 0CVE-2019-11884 – kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command
https://notcve.org/view.php?id=CVE-2019-11884
The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a '\0' character. La función do_hidp_sock_ioctl en net/bluetooth/hidp/sock.c en el kernel de Linux, versiones anteriores a 5.0.15, permite a un usuario local obtener información potencialmente sensible de la memoria de la pila del kernel a través de un comando HIDPCONNNADD, ya que un campo de nombre puede no terminar con un carácter ` \0'. A flaw was found in the Linux kernel's implementation of the Bluetooth Human Interface Device Protocol (HIDP). A local attacker with access permissions to the Bluetooth device can issue an IOCTL which will trigger the do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c.c. This function can leak potentially sensitive information from the kernel stack memory via a HIDPCONNADD command because a name field may not be correctly NULL terminated. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html http://www.securityfocus.com/bid/108299 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://access.redhat.com/errata/RHSA-2020:0740 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.15 https://g • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
