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
cedrus remove() function in the drivers/staging/media/sunxi/cedrus/cedrus.c module of 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.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
cedrus remove() function until a patch is available. Restrict access to the vulnerable module drivers/staging/media/sunxi/cedrus/cedrus.c to minimize the risk of exploitation.Correção
