patch available.

  - In the Linux kernel, the following vulnerability has been resolved: acpi: nfit: vmalloc-out-of-bounds Read
    in acpi_nfit_ctl Fix an issue detected by syzbot with KASAN: BUG: KASAN: vmalloc-out-of-bounds in
    cmd_to_func drivers/acpi/nfit/ core.c:416 [inline] BUG: KASAN: vmalloc-out-of-bounds in
    acpi_nfit_ctl+0x20e8/0x24a0 drivers/acpi/nfit/core.c:459 The issue occurs in cmd_to_func when the
    call_pkg->nd_reserved2 array is accessed without verifying that call_pkg points to a buffer that is
    appropriately sized as a struct nd_cmd_pkg. This can lead to out-of-bounds access and undefined behavior
    if the buffer does not have sufficient space. To address this, a check was added in acpi_nfit_ctl() to
    ensure that buf is not NULL and that buf_len is less than sizeof(*call_pkg) before accessing it. This
    ensures safe access to the members of call_pkg, including the nd_reserved2 array. (CVE-2024-56662)

Note that Nessus relies on the presence of the package as reported by the vendor.");
