CVE-2022-49030
In the Linux kernel, the following vulnerability has been resolved:
libbpf: Handle size overflow for ringbuf mmap
The maximum size of ringbuf is 2GB on x86-64 host, so 2 * max_entries
will overflow u32 when mapping producer page and data pages. Only
casting max_entries to size_t is not enough, because for 32-bits
application on 64-bits kernel the size of read-only mmap region
also could overflow size_t.
So fixing it by casting the size of read-only mmap region into a __u64
and checking whether or not there will be overflow during mmap.
