EIP-2026-103034 EXPLOITDB ruby WORKING POC
VMware Workstation - ALSA Config File Local Privilege Escalation (Metasploit)
CVE-2019-9213 EXPLOITDB MEDIUM ruby WORKING POC
Reliable Datagram Sockets (RDS) rds_atomic_free_op NULL pointer dereference Privilege Escalation
In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task.
CVSS 5.5
CVE-2019-13272 EXPLOITDB HIGH ruby WORKING POC
Linux Polkit pkexec helper PTRACE_TRACEME local root exploit
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.

CVE-2018-18955 EXPLOITDB HIGH bash WORKING POC
Linux Nested User Namespace idmap Limit Local Privilege Escalation
In the Linux kernel 4.15.x through 4.19.x before 4.19.2, map_write() in kernel/user_namespace.c allows privilege escalation because it mishandles nested user namespaces with more than 5 UID or GID ranges. A user who has CAP_SYS_ADMIN in an affected user namespace can bypass access controls on resources outside the namespace, as demonstrated by reading /etc/shadow. This occurs because an ID transformation takes place properly for the namespaced-to-kernel direction but not for the kernel-to-namespaced direction.

CVE-2017-16995 EXPLOITDB HIGH ruby WORKING POC
Linux BPF Sign Extension Local Privilege Escalation
The check_alu_op function in kernel/bpf/verifier.c in the Linux kernel through 4.4 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging incorrect sign extension.

CVE-2019-2215 EXPLOITDB HIGH ruby WORKING POC
Android Binder Use-After-Free Exploit
A use-after-free in binder.c allows an elevation of privilege from an application to the Linux Kernel. No user interaction is required to exploit this vulnerability, however exploitation does require either the installation of a malicious local application or a separate vulnerability in a network facing application.Product: AndroidAndroid ID: A-141720095

CVE-2017-13209 EXPLOITDB HIGH text WORKING POC
Google Android - Missing Authorization
In the ServiceManager::add function in the hardware service manager, there is an insecure permissions check based on the PID of the caller which could allow an application or service to replace a HAL service with its own service. This could lead to a local elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: 8.0, 8.1. Android ID: A-68217907.
