CriticalCVSS 9.8/10Last modified Jun 17, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

smb: server: avoid double-free in smb_direct_free_sendmsg after smb_direct_flush_send_list()

smb_direct_flush_send_list() already calls smb_direct_free_sendmsg(), so we should not call it again after post_sendmsg() moved it to the batch list.
