DEBIAN-CVE-2022-49557

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: KVM: Set the base guest FPU uABI size to sizeofstruct kvmxsave Set the starting uABI size of KVM's guest FPU to 'struct kvmxsave', i.e. to KVM's historical uABI size. When saving FPU state for usersapce, KVM well, now th...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from not properly handling the XSAVE header during FPU state saving, which could lead to out-of-bounds writes and...

CVE-2021-47227

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Prevent state corruption in fpurestoresig The non-compacted slowpath uses copyfromuser and copies the entire user buffer into the kernel buffer, verbatim. This means that the kernel buffer may now contain entirely invali...

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Prevent state corruption in fpurestoresig The non-compacted slowpath uses copyfromuser and copies the entire user buffer into the kernel buffer, verbatim. This means that the kernel buffer may now contain entirely invali...

CVE-2021-47227

The CVE-2021-47227 issue concerns the Linux kernel x86 fpu path: the non‑compacted slowpath could copy a user XSAVE buffer into kernel space via __copy_from_user(), potentially leaving the kernel XSAVE buffer in an invalid state that XRSTOR could fault on. The identified root cause is improper ha...
