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 in the Linux kernel's radeon driver, specifically in the radeon_cs_parser_init function. When the size variable is set to 0x40000000, multiplying it by the size of uint32_t causes the size to overflow and become zero. This leads to referencing uninitialized memory later in the code, which can cause unexpected behavior or crashes.
How can this vulnerability impact me? :
The integer overflow can cause the system to reference uninitialized memory, potentially leading to system instability, crashes, or unexpected behavior when using the affected radeon driver in the Linux kernel.
