Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bpf: Check bloom filter map value size<br /> <br /> This patch adds a missing check to bloom filter creating, rejecting<br /> values above KMALLOC_MAX_SIZE. This brings the bloom map in line with<br /> many other map types.<br /> <br /> The lack of this protection can cause kernel crashes for value sizes<br /> that overflow int&amp;#39;s. Such a crash was caught by syzkaller. The next<br /> patch adds more guard-rails at a lower level.
