UBUNTU-CVE-2025-21632

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Ensure shadow stack is active before "getting" registers The x86 shadow stack support has its own set of registers. Those registers are XSAVE-managed, but they are "supervisor state components" which means that userspace...

CVE-2025-21632

CVE-2025-21632: In the Linux kernel, a patch fixes shadow stack handling for x86 XSAVE state accessed via ptrace. Previously, regset get/set paths could be invoked with shadow stacks disabled (ARCH_SHSTK_SHSTK==0), causing get_xsave_addr() to return NULL and trigger a WARN_ON in ssp_get. The fix ...
