CVE-2026-93159

CVE-2026-93159 affects the atmel-sha204a hardware RNG driver in the Linux kernel . In the nonblocking RNG path, a work_data structure is allocated to track in-flight asynchronous I2C requests and stored in rng->priv. If the I2C transfer fails, the previous code only logged a warning but left t...

EUVD-2026-82267

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 workdata structure to track the state of an in-flight asynchronous I2C request. This pointer is stored in rng-priv and later...

The vulnerability of the `atmel_sha204a_rng_readnonblocking()` function in the `drivers/crypto/atmel-sha204a.c` driver of the Linux kernel cryptographic accelerator allows a hacker to cause a system failure.

The vulnerability of the atmelsha204arngreadnonblocking function in the drivers/crypto/atmel-sha204a.c driver of the Linux kernel’s cryptographic accelerator module is related to unlimited resource allocation. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

CVE-2026-74402

A flaw was found in the Linux kernel's atmel-sha204a cryptographic hardware random number generator HWRNG driver. Improper buffer management in both blocking and non-blocking paths causes the driver to fail in providing valid entropy. This occurs because the buffer is read starting from byte 1, a...
