Exploitability
| CWE ID | Description |
|---|---|
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an integer overflow flaw in the RandR extension of the xorg-x11-server, specifically in the RRChangeProviderProperty function. It occurs because the function does not properly validate input from clients, leading to incorrect calculations of memory allocation size. This can cause memory corruption on affected Linux systems. [1]
How can this vulnerability impact me? :
The vulnerability can lead to memory corruption, which poses a high-severity security risk. Exploiting this flaw could potentially allow an attacker with local access to cause denial of service or other impacts related to memory corruption on affected Linux systems. [1]
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should update or patch the xorg-x11-server package, especially the Xwayland and tigervnc components, to versions that fix the integer overflow in the RRChangeProviderProperty function. Applying vendor-provided security updates promptly is recommended to prevent potential exploitation and memory corruption. [1]
