| Vetor | AV:N/AC:M/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.6
Description
The issue is related to a race condition in the ion ioctl function, which can be exploited by calling ION IOC FREE on two CPUs simultaneously, potentially allowing local users to gain privileges or cause a denial of service due to a use-after-free condition.
Recommendations
For Linux kernel versions prior to 4.6, update to version 4.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the ion ioctl function to minimize the risk of exploitation.
