11) Double Free (CVE-ID: CVE-2022-2588)
The vulnerability allows a local user to escalate privileges on the system.
The
vulnerability exists due to a double free error within the network packet scheduler implementation
in the route4_change() function in Linux kernel when removing all references to a route filter
before freeing it. A local user can run a specially crafted program to
crash the kernel or execute arbitrary code.
12) Use-after-free (CVE-ID: CVE-2021-4203)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in sock_getsockopt() function in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() function (and connect() function) in the Linux kernel. A local user can exploit the use-after-free error and crash the system or escalate privileges on the system.
13) Use-after-free (CVE-ID: CVE-2020-21913)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the pkg_createWithAssemblyCode() function in the file tools/pkgdata/pkgdata.cpp. A remote attacker can trick the victim to open a specially crafted file and perform a denial of service (DoS) attack.
14) Input validation error (CVE-ID: CVE-2017-0386)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An elevation of privilege vulnerability in the libnl library could enable a local malicious application to execute arbitrary code within the context of a privileged process. This issue is rated as High because it could be used to gain local access to elevated capabilities, which are not normally accessible to a third-party application. Product: Android. Versions: 5.0.2, 5.1.1, 6.0, 6.0.1, 7.0, 7.1. Android ID: A-32255299.
15) Input validation error (CVE-ID: CVE-2022-35252)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an
HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.
16) Out-of-bounds write (CVE-ID: CVE-2020-12762)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the "printbuf_memappend". A remote attacker can create a specially crafted JSON file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
17) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-31676)
The vulnerability allows a local user to escalate privileges on the system.
