The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ceph: add a bunch of missing ceph_path_info initializers ceph_mdsc_build_path() must be called with a     zero-initialized ceph_path_info parameter, or else the following ceph_mdsc_free_path_info() may crash.
    Example crash (on Linux 6.18.12): virt_to_cache: Object is not a Slab page! WARNING: CPU: 184 PID: 2871736     at mm/slub.c:6732 kmem_cache_free+0x316/0x400 [...] Call Trace: [...] ceph_open+0x13d/0x3e0     do_dentry_open+0x134/0x480 vfs_open+0x2a/0xe0 path_openat+0x9a3/0x1160 [...] cache_from_obj: Wrong slab     cache. names_cache but object is from ceph_inode_info WARNING: CPU: 184 PID: 2871736 at mm/slub.c:6746     kmem_cache_free+0x2dd/0x400 [...] kernel BUG at mm/slub.c:634! Oops: invalid opcode: 0000 [#1] SMP NOPTI     RIP: 0010:__slab_free+0x1a4/0x350 Some of the ceph_mdsc_build_path() callers had initializers, but others     had not, even though they were all added by commit 15f519e9f883 (ceph: fix race condition validating     r_parent before applying state). The ones without initializer are suspectible to random crashes. (I can     imagine it could even be possible to exploit this bug to elevate privileges.) Unfortunately, these Ceph     functions are undocumented and its semantics can only be derived from the code. I see that     ceph_mdsc_build_path() initializes the structure only on success, but not on error. Calling     ceph_mdsc_free_path_info() after a failed ceph_mdsc_build_path() call does not even make sense, but that's     what all callers do, and for it to be safe, the structure must be zero-initialized. The least intrusive     approach to fix this is therefore to add initializers everywhere. (CVE-2026-43408)

Note that Nessus relies on the presence of the package as reported by the vendor.
