Descriptions

In the Linux kernel, the following vulnerability has been resolved: dma-buf: Fix NULL pointer dereference in sanitycheck() If due to a memory allocation failure mock_chain() returns NULL, it is
passed to dma_fence_enable_sw_signaling() resulting in NULL pointer
dereference there. Call dma_fence_enable_sw_signaling() only if mock_chain() succeeds. Found by Linux Verification Center (linuxtesting.org) with SVACE.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dma-buf: corrige la desreferencia del puntero NULL en sanitycheck(). Si debido a un error en la asignación de memoria, mock_chain() devuelve NULL, se pasa a dma_fence_enable_sw_signaling(), lo que genera una desreferencia del puntero NULL allí. . Llame a dma_fence_enable_sw_signaling() solo si mock_chain() tiene éxito. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.
