Ubuntu Security Notice USN-6608-1
Posted Jan 26, 2024
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 6608-1 - It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information. Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did not properly handle inactive elements in its PIPAPO data structure, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Proof of concept exploit for a privilege escalation issue in Android. In checkDebuggingDisallowed of DeviceVersionFragment.java, there is a possible way to access adb before SUW completion due to an insecure default value. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
