[PATCH OLK-5.10 v2] loop: Avoid updating block size under exclusive owner
by Zheng Qixing 26 Sep '25

26 Sep '25

From: Jan Kara <jack(a)suse.cz> mainline inclusion from mainline-v6.17-rc1 commit 7e49538288e523427beedd26993d446afef1a6fb category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICWGGN CVE: CVE-2025-38709 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------ Syzbot came up with a reproducer where a loop device block size is changed underneath a mounted filesystem. This causes a mismatch between the block device block size and the block size stored in the superblock causing confusion in various places such as fs/buffer.c. The particular issue triggered by syzbot was a warning in __getblk_slow() due to requested buffer size not matching block device block size. Fix the problem by getting exclusive hold of the loop device to change its block size. This fails if somebody (such as filesystem) has already an exclusive ownership of the block device and thus prevents modifying the loop device under some exclusive owner which doesn't expect it.

[PATCH OLK-5.10] NFSD: Protect against send buffer overflow in NFSv3 READ
by Li Lingfeng 26 Sep '25

26 Sep '25

From: Chuck Lever <chuck.lever(a)oracle.com> mainline inclusion from mainline-v6.1-rc1 commit fa6be9cc6e80ec79892ddf08a8c10cabab9baf38 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICYBVR CVE: CVE-2022-50345 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffers into a single array of pages. This works because there are no cases where an operation needs a large RPC Call message and a large RPC Reply at the same time. Once an RPC Call has been received, svc_process() updates svc_rqst::rq_res to describe the part of rq_pages that can be used for constructing the Reply. This means that the send buffer (rq_res) shrinks when the received RPC record containing the RPC Call is large. A client can force this shrinkage on TCP by sending a correctly- formed RPC Call header contained in an RPC record that is excessively large. The full maximum payload size cannot be constructed in that case.
