[PATCH openEuler-1.0-LTS] nfc: pn533: Wait for out_urb's completion in pn533_usb_send_frame()
by Kaixiong Yu 24 Aug '24

From: Minsuk Kang <linuxlovemin(a)yonsei.ac.kr> stable inclusion from stable-v4.19.270 commit 321db5131c92983dac4f3338e8fbb6df214238c0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IALIN1 CVE: CVE-2023-52907 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 9dab880d675b9d0dd56c6428e4e8352a3339371d ] Fix a use-after-free that occurs in hcd when in_urb sent from pn533_usb_send_frame() is completed earlier than out_urb. Its callback frees the skb data in pn533_send_async_complete() that is used as a transfer buffer of out_urb. Wait before sending in_urb until the callback of out_urb is called. To modify the callback of out_urb alone, separate the complete function of out_urb and ack_urb. Found by a modified version of syzkaller.

Then unpoison_memory() can unpoison the page and send the buddy page back into buddy list again leading to the above bad page state warning. And bad_page() will call page_mapcount_reset() to remove PageBuddy from buddy page leading to later VM_BUG_ON_PAGE(!PageBuddy(page)) when trying to allocate this page. Fix this issue by only treating __page_handle_poison() as successful when it returns 1.
