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: nfsd: initialize copy-notify stateid
 before publishing it nfsd4_copy_notify() finished initializing the cpntf state after
 nfs4_alloc_init_cpntf_state() had already linked it into the s2s_cp_stateids IDR and the parent's
 sc_cp_list, with cs_count == 1 (the membership reference) and none held for the caller. A racing
 OFFLOAD_CANCEL (crafted cl_id == nn->s2s_cp_cl_id plus the guessable so_id) could reach
 manage_cpntf_state() and free the entry, turning the caller's subsequent cpn_cnr_stateid read and
 cp_p_stateid/cp_p_clid writes into use-after-free. The owning clientid was also only recorded after
 publication, so it could not gate an ownership check in that window. Record cp_p_stateid and cp_p_clid
 inside nfs4_alloc_init_cpntf_state() before nfs4_init_cp_state() publishes the entry, and return it with
 an extra reference. The caller reads the stateid under that reference and drops it with
 nfs4_put_cpntf_state(); on a late error the laundromat reaps the entry. (CVE-2026-89669)

Solution

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