- Summary
- bpf: Check bloom filter map value size
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bpf: Check bloom filter map value size
This patch adds a missing check to bloom filter creating, rejecting values above KMALLOC_MAX_SIZE. This brings the bloom map in line with many other map types.
The lack of this protection can cause kernel crashes for value sizes that overflow int's. Such a crash was caught by syzkaller. The next patch adds more guard-rails at a lower level.
