A critical use-after-free vulnerability (CVE-2025-68263) in the Linux kernel's ksmbd IPC subsystem was resolved. The flaw involved a race condition where ipc_msg_send_request() could free memory while another handler was still accessing it, leading to a slab-use-after-free detected by KASAN. This vulnerability affects Linux kernel versions prior to certain 5.15.x releases on Ubuntu 20.04.1. The issue has been fixed by ensuring proper locking around the shared data structures. The vulnerability has a CVSS score of 9.8, indicating high impact on confidentiality, integrity, and availability. A patch is available and users are advised to update and reboot to apply the fix. The vendor advisory also covers many other Linux kernel vulnerabilities fixed in the same update.

The Linux kernel's ksmbd IPC subsystem contained a use-after-free vulnerability (CVE-2025-68263) caused by a race condition between ipc_msg_send_request() and the generic netlink handler functions (handle_generic_event()/handle_response()). ipc_msg_send_request() waited for a netlink reply using a stack-allocated ipc_msg_table_entry. The handler filled entry->response under a lock, but ipc_msg_send_request() validated and freed entry->response without holding the same lock. Under high concurrency, this led to a race where handle_response() could write to freed memory, causing a slab-use-after-free detected by KASAN. The fix involved taking the ipc_msg_table_lock in ipc_msg_send_request() during validation and freeing to prevent concurrent access. This vulnerability affects Linux kernel versions prior to 5.15.0-1111.118~20.04.1 and related versions on Ubuntu 20.04.1. The CVSS 3.1 score is 9.8 (critical) with network attack vector, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. The vendor has released patches and advises updating to fixed kernel versions and rebooting. The advisory also addresses numerous other kernel vulnerabilities in the same update.
