Description

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Clear queue->active_job when v3d_fence_create() fails The run_job() callbacks for BIN, RENDER, TFU and CSD assign the incoming job to queue->active_job before calling v3d_fence_create(). If v3d_fence_create() fails, the callback returns NULL without clearing active_job, leaving a dangling pointer. Create a failure path in all run_job() callbacks that clears the active job before returning NULL. The BIN path takes queue->queue_lock around the clear as it races against v3d_overflow_mem_work(); RENDER, TFU and CSD paths have no concurrent reader, so the clear is lock-free.

CVE-2026-93157

In the Linux kernel, the following vulnerability has been resolved: hwrng: xilinx-trng - propagate timeout before any data is read xtrng_readblock32() polls for 16-byte chunks but returns the number of bytes read even when the first poll times out. Its caller then treats a zero return as a short successful read, and partial reads for full 32-byte blocks can make the tail copy use a fixed block offset rather than the amount already produced. Return the poll error when no data has been read, preserve partial positive returns after some data is available, stop the generator on all collection exits, and append tail bytes at the current output count.

CVE-2026-93159

In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-sha204a - fix heap info leak on I2C transfer failure The nonblocking RNG path allocates a work_data structure to track the state of an in-flight asynchronous I2C request. This pointer is stored in rng->priv and later consumed by the read path once the transaction completes. If the underlying I2C transfer fails, the completion callback is invoked with a non-zero status. In this case, the allocated work_data is not usable for producing RNG output and must not remain associated with the hwrng state. Previously, the failure path only logged a warning but left the pointer state uncleared, which can result in subsequent read attempts observing stale state and interpreting it as valid completion data. Fix this by freeing the pending work_data. The I2C transaction reports an error. This ensures that failed requests do not leave residual state behind that could be interpreted as valid RNG data on later reads. Clearing rng->priv is done at the subsequent call to nonblocking read.

CVE-2026-93160

The Linux kernel’s Atmel ECC driver now checks that a public key is cached before performing a hardware ECDH operation. Previously, the driver could use a private key that wasn’t generated for the current transformation, potentially allowing misuse of keys.
