CVE-2024-42156

The CVE-2024-42156 issue concerns the Linux kernel s390/pkey code, where copies of clear-key structures are wiped on failure. The underlying flaw wipes sensitive data from the stack for all IOCTLs converting a clear-key into a protected- or secure-key, exposing confidentiality risk. Documents con...

kernel: ALSA: pcm: Fix races among concurrent hw_params and hw_free calls

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix races among concurrent hwparams and hwfree calls Currently we have neither proper check nor protection against the concurrent calls of PCM hwparams and hwfree ioctls, which may result in a UAF. Since the existing P...
