Title
libceph: replace overzealous BUG_ON in osdmap_apply_incremental()
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.

A remote malicious or compromised Ceph peer can supply the malformed incremental map.\nAC:L - The trigger is a straightforward epoch mismatch inside an otherwise accepted incremental OSD map. No race, timing window, or hard-to-control memory layout is required.\nPR:N - The attacker does not need privileges on the vulnerable Linux client; the relevant gate is being the network peer that sends the Ceph map. Ceph authentication/fsid checks may restrict which peers are trusted, but in the highest reasonable scenario a malicious or compromised cluster peer can send the map without local target privileges.\nUI:N - Once the client is connected and subscribed to OSD map updates, the peer can send the malformed map without any further victim action. The crash is caused by network message processing in the kernel worker path.\nS:U - The impact is a crash of the vulnerable kernel/client system itself. It does not cross into a separate security authority such as guest-to-host or IOMMU escape.\nC:N - The bug is an overzealous BUG_ON on an epoch consistency check. It does not expose memory or create a read primitive.\nI:N - The fix only changes a fatal assertion into invalid-map handling. There is no memory corruption, arbitrary write, or data modification primitive.\nA:H - The vulnerable code executes BUG_ON when the crafted epoch differs from map-\u003eepoch + 1. That can panic/oops the kernel, causing high availability impact."
