CVE-2018-5333 – Reliable Datagram Sockets (RDS) - rds_atomic_free_op NULL pointer dereference Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-5333
In the Linux kernel through 4.14.13, the rds_cmsg_atomic function in net/rds/rdma.c mishandles cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference. En el kernel de Linux hasta la versión 4.14.13, la función rds_cmsg_atomic en net/rds/rdma.c gestiona de manera incorrecta los casos en los que fracasa la asignación de páginas o cuando se proporciona una dirección no válida, lo que conduce a una desreferencia de puntero NULL en rds_atomic_free_op. In the Linux kernel through 4.14.13, the rds_cmsg_atomic() function in 'net/rds/rdma.c' mishandles cases where page pinning fails or an invalid address is supplied by a user. This can lead to a NULL pointer dereference in rds_atomic_free_op() and thus to a system panic. • https://www.exploit-db.com/exploits/47957 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7d11f77f84b27cef452cee332f4e469503084737 http://packetstormsecurity.com/files/156053/Reliable-Datagram-Sockets-RDS-rds_atomic_free_op-Privilege-Escalation.html http://www.securityfocus.com/bid/102510 https://access.redhat.com/errata/RHSA-2018:0470 https://github.com/torvalds/linux/commit/7d11f77f84b27cef452cee332f4e469503084737 https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https: • CWE-476: NULL Pointer Dereference •
CVE-2018-5344 – kernel: drivers/block/loop.c mishandles lo_release serialization allowing denial-of-service
https://notcve.org/view.php?id=CVE-2018-5344
In the Linux kernel through 4.14.13, drivers/block/loop.c mishandles lo_release serialization, which allows attackers to cause a denial of service (__lock_acquire use-after-free) or possibly have unspecified other impact. En el kernel de Linux hasta la versión 4.14.13, drivers/block/loop.c gestiona de manera incorrecta la serialización de lo_release, lo que permite que atacantes provoquen una denegación de servicio (uso de memoria previamente liberada de __lock_acquire) o, posiblemente, otro impacto sin especificar. A flaw was found in the Linux kernel's handling of loopback devices. An attacker, who has permissions to setup loopback disks, may create a denial of service or other unspecified actions. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ae6650163c66a7eff1acd6eb8b0f752dcfa8eba5 http://www.securityfocus.com/bid/102503 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://github.com/torvalds/linux/commit/ae6650163c66a7eff1acd6eb8b0f752dcfa8eba5 https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 https://usn.ubuntu.com/3617-1 https://usn.ubuntu • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

The WLAN (aka Wi-Fi) driver for the Linux kernel 3.x and 4.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not verify authorization for private SET IOCTL calls, which allows attackers to gain privileges via a crafted application, related to wlan_hdd_hostapd.c and wlan_hdd_wext.c. El controlador WLAN (también conocido como Wi-Fi) para el kernel de Linux 3.x y 4.x, según se utiliza en Qualcomm Innovation Center (QuIC) Android contributions for MSM devices y otros productos, no verifica la autorización para llamadas SET IOCTL privadas, lo que permite a atacantes obtener privilegios a través de una aplicación manipulada, relacionado con wlan_hdd_hostapd.c y wlan_hdd_wext.c. • http://source.android.com/security/bulletin/2016-05-01.html http://www.securityfocus.com/bid/77691 https://www.codeaurora.org/projects/security-advisories/multiple-issues-wlan-driver-allow-local-privilege-escalation-cve-2015 • CWE-862: Missing Authorization •
CVE-2016-2854 – AUFS (Ubuntu 15.10) - 'allow_userns' Fuse/Xattr User Namespaces Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-2854
The aufs module for the Linux kernel 3.x and 4.x does not properly maintain POSIX ACL xattr data, which allows local users to gain privileges by leveraging a group-writable setgid directory. El módulo aufs para el kernel de Linux 3.x y 4.x no mantiene correctamente datos POSIX ACL xattr, lo que permite a usuarios locales obtener privilegos aprovechando un directorio con permiso de escritura de grupo setgid. AUFS (Ubuntu 15.10) suffers from an allow_userns fuse/xattr user namespaces privilege escalation vulnerability. • https://www.exploit-db.com/exploits/41761 http://www.halfdog.net/Security/2016/AufsPrivilegeEscalationInUserNamespaces http://www.openwall.com/lists/oss-security/2016/02/24/9 http://www.securityfocus.com/bid/96838 https://sourceforge.net/p/aufs/mailman/message/34864744 • CWE-269: Improper Privilege Management •
