[PATCH OLK-5.10] NFSD: Protect against send buffer overflow in NFSv3 READ

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.

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.

[openEuler-1.0-LTS] [Backport] wifi: mwifiex: avoid possible NULL skb pointer dereference
by Zhang Yuwei 26 Sep '25

From: Dmitry Antipov <dmantipov(a)yandex.ru> mainline inclusion from mainline-v6.6-rc1 commit 35a7a1ce7c7d61664ee54f5239a1f120ab95a87e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICYQMB CVE: CVE-2023-53384 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit 35a7a1ce7c7d61664ee54f5239a1f120ab95a87e ] In 'mwifiex_handle_uap_rx_forward()', always check the value returned by 'skb_copy()' to avoid potential NULL pointer dereference in 'mwifiex_uap_queue_bridged_pkt()', and drop original skb in case of copying failure. Found by Linux Verification Center (linuxtesting.org) with SVACE.
