Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-05-27 15:33

Details

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

crypto: atmel-sha204a - Fix potential UAF and memory leak in remove path

Unregister the hwrng to prevent new ->read() calls and flush the Atmel I2C workqueue before teardown to prevent a potential UAF if a queued callback runs while the device is being removed.

Drop the early return to ensure sysfs entries are removed and ->hwrng.priv is freed, preventing a memory leak.
