Description
In the Linux kernel, the following vulnerability has been resolved:
smb: client: avoid double-free in smbd_free_send_io() after smbd_send_batch_flush()
smbd_send_batch_flush() already calls smbd_free_send_io(),
so we should not call it again after smbd_post_send()
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)
