CVE-2021-47305

In CVE-2021-47305, the Linux kernel’s dma-buf/sync_file implementation leaks fences on error paths due to missing dma_fence_put() calls when merging fences and in krealloc_array failure. The fix ensures i and the fences array are zero-initialized and that all fences are dma_fence_put() and the fe...

CVE-2021-47305

In the Linux kernel, the following vulnerability has been resolved: dma-buf/syncfile: Don't leak fences on merge failure Each addfence call does a dmafenceget on the relevant fence. In the error path, we weren't calling dmafenceput so all those fences got leaked. Also, in the kreallocarray failur...
