Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.3.2
Description
The issue is related to a use-after-free vulnerability in the
rkvdec remove() function within the Rockchip Video Decoder driver in the Linux kernel. This vulnerability is caused by a race condition due to concurrent access to a resource, allowing an attacker to potentially impact the confidentiality, integrity, and availability of protected information. A proof-of-concept exploit has been discovered, which can silently execute a malicious bash script disguised as a kernel-level process.Recommendations
For Linux kernel versions prior to 6.3.2, update to version 6.3.2 or later to resolve the issue.
As a temporary workaround, consider disabling the
rkvdec remove() function until a patch is available.Exploit
