CVE-2025-38533
|
| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
net: libwx: fix the using of Rx buffer DMA
The wx_rx_buffer structure contained two DMA address fields: 'dma' and
'page_dma'. However, only 'page_dma' was actually initialized and used
to program the Rx descriptor. But 'dma' was uninitialized and used in
some paths.
This could lead to undefined behavior, including DMA errors or
use-after-free, if the uninitialized 'dma' was used. Althrough such
error has not yet occurred, it is worth fixing in the code. |
