The vulnerability of the __fpu__restore_sig() function in the arch/x86/kernel/fpu/signal.c module, which supports Linux’s x86 kernel-based operating system, allows a hacker to trigger a service failure.

The vulnerability of the fpurestoresig function in the arch/x86/kernel/fpu/signal.c module of the Linux operating system’s kernel support for the x86 platform is related to incorrect input validation. Exploiting this vulnerability could allow an attacker to cause a service failure...

kernel: x86/fpu: Stop relying on userspace for info to fault in xsave buffer that cause loop forever

A flaw was found in the Linux kernel's x86/fpu module, which revolves around an issue with relying on user space for critical information regarding the xsave buffer. In the affected scenario, the expected size of the user space buffer is derived from user-controlled data, specifically,...
