A flaw was found in the Linux kernel, specifically within the s390/pkey component. This vulnerability occurs because the `pkey_pckmo` handler function does not explicitly check the length of the target buffer. If the generated output data exceeds the provided buffer's length, the handler function fails. This could allow a local attacker to cause a denial of service.

In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Check length in pkey_pckmo handler implementation Explicitly check the length of the target buffer in the pkey_pckmo implementation of the key_to_protkey() handler function. The handler function fails, if the generated output data exceeds the length of the provided target buffer.
