Description
This security bulletin contains information about 33 secuirty vulnerabilities.
1) Null pointer dereference (CVE-ID: CVE-2017-16537)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists due to NULL pointer dereference in the imon_probe function in drivers/media/rc/imon.c. A local attacker can use a specially crafted USB device and cause the system to crash.
Successful exploitation of the vulnerability results in denial of service.
2) Use-after-free (CVE-ID: CVE-2018-9422)
The vulnerability allows a local authenticated user to execute arbitrary code.
In get_futex_key of futex.c, there is a use-after-free due to improper locking. This could lead to local escalation of privilege with no additional privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-74250718 References: Upstream kernel.
3) Information disclosure (CVE-ID: CVE-2021-45486)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to incorrect implementation of the IPv4 protocol in the Linux kernel. A remote attacker can disclose internal state in some situations.
4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-2503)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to the way dm-verity is used to restrict module/firmware loads to trusted root filesystem in LoadPin builds. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates.
5) Information disclosure (CVE-ID: CVE-2022-0850)
