Date: Mon, 6 Jul 2026 16:52:12 +0800	[thread overview]
Message-ID: <e6003504-96f1-4dc8-9e6b-e17c8f809d75@amlogic.com> (raw)

Dear maintainers,

A f2fs patch should be backported from upstream mainline to the stable
5.15.y branches. The patch's information is shown as below:

[Subject]
f2fs: fix UAF issue in f2fs_merge_page_bio()

[Upstream commit ID]
edf7e9040fc52c922db947f9c6c36f07377c52ea

[Kernel version]
5.15.y

[Why]
We encountered the same issue on the 5.15 kernel version. After 
referring to the modifications in the upstream, the issue was solved.




Thanks,
Jiucheng
