<sandeen@redhat.com> # Date: Wed Oct 17 15:23:59 2018 +0100 # # fscache: Fix out of bound read in long cookie keys # # fscache_set_key() can incur an out-of-bounds read, reported by KASAN: # # BUG: KASAN: slab-out-of-bounds in fscache_alloc_cookie+0x5b3/0x680 [fscache] # Read of size 4 at addr ffff88084ff056d4 by task mount.nfs/32615 # # and also reported by syzbot at https://lkml.org/lkml/2018/7/8/236 # # BUG: KASAN: slab-out-of-bounds in fscache_set_key fs/fscache/cookie.c:120 [inline] # BUG: KASAN: slab-out-of-bounds in fscache_alloc_cookie+0x7a9/0x880 fs/fscache/cookie.c:171 # Read of size 4 at addr ffff8801d3cc8bb4 by task syz-executor907/4466 # # This happens for any index_key_len which is not divisible by 4 and is # larger than the size of the inline key, because the code allocates exactly # index_key_len for the key buffer, but the hashing loop is stepping through # it 4 bytes (u32) at a time in the buf[] array. # # Fix this by calculating how many u32 buffers we'll need by using # DIV_ROUND_UP, and then using kcalloc() to allocate a precleared allocation # buffer to hold the index_key, then using that same count as the hashing # index limit. # # Fixes: ec0328e46d6e ("fscache: Maintain a catalogue of allocated cookies") # Reported-by: syzbot+a95b989b2dde8e806af8@syzkaller.appspotmail.com # Signed-off-by: Eric Sandeen
