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: smb: client: cancel reconnect work in
 clean_demultiplex_info() clean_demultiplex_info() cancels server->echo delayed work but not
 server->reconnect, which can cause a use-after-free when the demultiplex thread exits while a reconnect
 work is still queued: cifs_demultiplex_thread() cifs_readv_from_socket() cifs_reconnect()
 __cifs_reconnect() cifs_queue_server_reconn() mod_delayed_work(cifsiod_wq, &server->reconnect, 0)
 clean_demultiplex_info() cancel_delayed_work_sync(&server->echo) // echo canceled // reconnect NOT
 canceled kfree_sensitive(server) // server freed ...later, on cifsiod_wq: smb2_reconnect_server()
 server->srv_count // UAF read of freed server Fix this by canceling server->reconnect delayed work in
 clean_demultiplex_info() before the server is freed, the same way cifs_put_tcp_session() already does.
 (CVE-2026-98175)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.739.5 or later.
