Ubuntu.comUB:CVE-2024-36918CVE-2024-36918
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.
