In the Linux kernel, the following vulnerability has been resolved:

vfat: fix missing sb_min_blocksize() return value checks

When emulating an nvme device on qemu with both logical_block_size and
physical_block_size set to 8 KiB, but without format, a kernel panic
was triggered during the early boot stage while attempting to mount a
vfat filesystem.
