21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: memory: fsl_ifc: fix leak of private memory on probe failure On probe error the driver should free the memory allocated for private structure. Fix this by using resource-managed allocation. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: memoria: fsl_ifc: corrige la pérdida de memoria privada en caso de fallo de la sonda.

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: dma-buf/sync_file: Don't leak fences on merge failure Each add_fence() call does a dma_fence_get() on the relevant fence. In the error path, we weren't calling dma_fence_put() so all those fences got leaked. Also, in the krealloc_array failure case, we weren't freeing the fences array. Instead, ensure that i and fences are always zero-initialized and dma_fence_put() all the fences and kfree(fences) on every error path.
