In the Linux kernel, the following vulnerability has been resolved:
crypto: atmel-sha204a - Fix OOM ->tfm_count leak
If memory allocation fails, decrement ->tfm_count to avoid blocking
future reads.
A flaw was found in the Linux kernel's atmel-sha204a component. This issue arises when the system attempts to allocate memory, and that allocation fails. If not properly handled, a resource counter, tfm_count, is not correctly decremented, leading to a resource leak. This can be exploited by a local user or process to prevent future read operations, effectively causing a Denial of Service (DoS) by making the system unresponsive to certain requests.
