NVD Description

Note: Versions mentioned in the description apply only to the upstream libnbd package and not the libnbd package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in libnbd. A server can reply with a block size larger than 2^63 (the NBD spec states the size is a 64-bit unsigned value). This issue could lead to an application crash or other unintended behavior for NBD clients that doesn't treat the return value of the nbd_get_size() function correctly.
