CVE-2026-22990

Summary

In the Linux kernel, the following vulnerability has been resolved:

libceph: replace overzealous BUG_ON in osdmap_apply_incremental()

If the osdmap is (maliciously) corrupted such that the incremental osdmap epoch is different from what is expected, there is no need to BUG. Instead, just declare the incremental osdmap to be invalid.
