Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-12-02 03:31

Details

In the Linux kernel, the following vulnerability has been resolved:

dma-buf/dma-resv: Stop leaking on krealloc() failure

Currently dma_resv_get_fences() will leak the previously allocated array if the fence iteration got restarted and the krealloc_array() fails.

Free the old array by hand, and make sure we still clear the returned fences so the caller won't end up accessing freed memory. Some (but not all) of the callers of dma_resv_get_fences() seem to still trawl through the array even when dma_resv_get_fences() failed. And let's zero out num_fences as well for good measure.

Severity ?

5.5 (Medium)
