CVE-2021-47227

A vulnerability was found in the Linux kernel's x86/fpu, within the fpurestoresig function. When user data is copied into the kernel buffer without proper validation, it can lead to corruption of the kernel's state, resulting in a system crash when using the FPU. Mitigation Red Hat has investigat...
