      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: atmel-sha204a - fix heap info leak on I2C transfer failure\n\nThe nonblocking RNG path allocates a work_data structure to track the\nstate of an in-flight asynchronous I2C request. This pointer is stored\nin rng->priv and later consumed by the read path once the transaction\ncompletes.\n\nIf the underlying I2C transfer fails, the completion callback is invoked\nwith a non-zero status. In this case, the allocated work_data is not\nusable for producing RNG output and must not remain associated with the\nhwrng state.\n\nPreviously, the failure path only logged a warning but left the pointer\nstate uncleared, which can result in subsequent read attempts observing\nstale state and interpreting it as valid completion data.\n\nFix this by freeing the pending work_data. The I2C transaction reports\nan error. This ensures that failed requests do not leave residual state\nbehind that could be interpreted as valid RNG data on later reads.\nClearing rng->priv is done at the subsequent call to nonblocking read.",
