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: i2c: core: fix debugfs UAF on adapter
 removal i2c_del_adapter() frees the adapter's debugfs directory before it unregisters the adapter device,
 but the new_device sysfs attribute stays writable until device_del(). A write racing with removal still
 reaches i2c_device_probe(), which passes the freed adap->debugfs to debugfs_create_dir() as the new
 client's parent: BUG: KASAN: slab-use-after-free in lookup_noperm_common+0x407/0x430 Read of size 4 at
 addr ffff88803ef87810 by task syz.0.61/6090 lookup_noperm_common+0x407/0x430
 simple_start_creating+0x9c/0x110 debugfs_start_creating+0xdb/0x1a0 debugfs_create_dir+0x24/0x350
 i2c_device_probe+0x814/0xbf0 It's technically possible to create a client after i2c_deregister_clients has
 run. That client will never be unregistered and make wait_for_completion hang. Close the window by
 removing the new_device attribute at the start of i2c_del_adapter(). device_remove_file() will drain any
 clients left. (CVE-2026-89983)

Solution

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