Exploitability
| CWE ID | Description |
|---|---|
| CWE-416 | The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is in the Linux kernel's drm/hisilicon/hibmc component. It involves a local variable used as an irq name being passed to the request_irq() function. Because the variable is local, it leads to a use-after-free problem, causing request_irq() to fail. The fix was to use a global irq name variable instead of the local one.
How can this vulnerability impact me? :
The vulnerability can cause the request_irq() function to fail due to a use-after-free issue with the irq name variable. This failure could potentially disrupt the handling of interrupts in the affected component, possibly leading to system instability or malfunction in the drm/hisilicon/hibmc driver.
