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.
Affected configurations
• linux linux kernel (< 6.18.24)
• linux linux kernel (>= 6.19 < 6.19.14)
• linux linux kernel (>= 7.0 < 7.0.1)
