kernel: out-of-bounds read in set_fdc in drivers/block/floppy.c

An out-of-bounds OOB memory access flaw was found in the floppy driver module in the Linux kernel. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability i...
