CVE-2022-49557

CVE-2022-49557 affects the Linux kernel in x86/fpu/KVM. The root cause is KVM’s guest FPU uABI size being set to the host default instead of KVM’s historic size, causing out-of-bounds writes to the XSAVE header when saving FPU state for guests on hosts without XSAVE. This can lead to data corrupt...

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...

CVE-2022-49550 fs/ntfs3: provide block_invalidate_folio to fix memory leak

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: provide blockinvalidatefolio to fix memory leak The ntfs3 filesystem lacks the 'invalidatefolio' method and it causes memory leak. If you write to the filesystem and then unmount it, the cached written data are not free...
