In the Linux kernel, the following vulnerability has been resolved:
acpi: nfit: vmalloc-out-of-bounds Read in acpinfitctl
Fix an issue detected by syzbot with KASAN:
BUG: KASAN: vmalloc-out-of-bounds in cmdtofunc drivers/acpi/nfit/ core.c:416 [inline] BUG: KASAN: vmalloc-out-of-bounds in acpinfitctl+0x20e8/0x24a0 drivers/acpi/nfit/core.c:459
The issue occurs in cmdtofunc when the callpkg->ndreserved2 array is accessed without verifying that callpkg points to a buffer that is appropriately sized as a struct ndcmd_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 acpinfitctl() to ensure that buf is not NULL and that buflen is less than sizeof(*callpkg) before accessing it. This ensures safe access to the members of callpkg, including the ndreserved2 array.
