Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: NFSv4/pnfs: key the data server cache
on the NFS version nfs4_pnfs_ds_add() keys the per-net data server cache on the multipath address set
alone, and struct nfs4_pnfs_ds records no version. That suffices for the files layout driver, which always
connects with version 4, but flexfiles takes its version tuple from GETDEVICEINFO per device, and one
address can legitimately serve both NFSv3 and NFSv4. Two deviceids on one address with different
ds_versions[0].version therefore share a single nfs4_pnfs_ds, and whichever mirror connects first pins
ds_clp to its own version. The other one is handed that client anyway, so it selects rpc_call_ops for a
version the connection does not speak, and the mismatched sequence-slot handling dereferences NULL. Add
the version to the cache key so the two cannot alias, giving each version its own nfs4_pnfs_ds and
connection while both mirrors stay usable. Only the major version is compared, since that is what selects
rpc_call_ops and rpc_ops; v4.0 and v4.1 keep sharing a client. The files layout driver passes the 4 it
already hardcodes at connect time. (CVE-2026-90102)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
