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: gate nfs3 setacl by argp->mask
 nfsd3_proc_setacl() calls set_posix_acl() unconditionally for both ACL_TYPE_ACCESS and ACL_TYPE_DEFAULT,
 passing argp->acl_access and argp->acl_default verbatim. The NFSv3 ACL decoder only populates those
 pointers when the corresponding mask bit is set: nfs3svc_decode_setaclargs() if (args->mask & NFS_ACL)
 decode into acl_access if (args->mask & NFS_DFACL) decode into acl_default /* otherwise the pointer stays
 NULL (pc_argzero) */ nfsd3_proc_setacl() set_posix_acl(.., ACL_TYPE_ACCESS, argp->acl_access)
 set_posix_acl(.., ACL_TYPE_DEFAULT, argp->acl_default) set_posix_acl(idmap, dentry, type, NULL) is the VFS
 "remove this ACL type" operation. A NULL pointer that means "the client did not send this arm" is
 therefore indistinguishable from "the client asked to remove this ACL". A SETACL with mask=NFS_ACL
 silently drops the directory's default ACL; mask=0 drops both. The sibling nfsd3_proc_getacl() already
 consults argp->mask before touching each arm; mirror that in setacl. Fix by wrapping each set_posix_acl()
 call in the matching mask bit check and initializing error to 0 before inode_lock so that a request with
 neither bit set leaves the on-disk ACLs untouched and returns nfs_ok. The out_drop_lock path and the
 unconditional posix_acl_release() at out: are preserved; both NULL-tolerate the skipped arms.
 (CVE-2026-89671)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
