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