| Doc Text: |
A buffer-overflow vulnerability was found in the Linux kernel's udmabuf driver. The flaw occurs in the `udmabuf_create()` function, which calculates the page count limit (`pglimit`) using the variable `size_limit_mb`. This size variable can be misinterpreted as either 32-bit or 64-bit, resulting in incorrect page limit checks and allocating a larger DMA buffer than permitted. This issue can lead to memory corruption, system instability, and a denial of service.
