CVE-2026-93156

Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

crypto: rk3288 - fail ahash requests on HASH idle timeout

rk_hash_run() waits for RK_CRYPTO_HASH_STS to become idle after the final DMA transfer, but ignores the poll result. If the hash engine never becomes idle, the driver still reads the digest registers and finalizes the request with the previous success value.

Store the poll result and finalize the request with the timeout error before reading the digest registers.
