Description
Description
In the Linux kernel, the following vulnerability has been resolved:
accel/ethosu: fix job completion fence cleanup
ethosu_ioctl_submit_job() allocates done_fence before validating buffer
handles. Errors after allocation call ethosu_job_err_cleanup(), which frees
the job but leaks the uninitialized fence.
A scheduler dependency error also lets ethosu_job_run() return before
dma_fence_init(). Normal cleanup then passes a zeroed refcount to
dma_fence_put().
Release done_fence in the common cleanup path and use
dma_fence_was_initialized() to distinguish initialized fences from raw
allocations.
