[PATCH OLK-6.6] KVM: x86: use array_index_nospec with indices that come from guest
by Zhang Yuwei 11 Nov '25

From: Thijs Raymakers <thijs(a)raymakers.nl> stable inclusion from stable-v6.6.104 commit f49161646e03d107ce81a99c6ca5da682fe5fb69 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICYBRH Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c87bd4dd43a624109c3cc42d843138378a7f4548 upstream. min and dest_id are guest-controlled indices.

[PATCH OLK-6.6] software node: Correct a OOB check in software_node_get_reference_args()
by Zhang Yuwei 11 Nov '25

11 Nov '25

From: Zijun Hu <quic_zijuhu(a)quicinc.com> stable inclusion from stable-v6.6.95 commit f9397cf7bfb680799fb8c7f717c8f756384c3280 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICLICJ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 31e4e12e0e9609850cefd4b2e1adf782f56337d6 ] software_node_get_reference_args() wants to get @index-th element, so the property value requires at least '(index + 1) * sizeof(*ref)' bytes but that can not be guaranteed by current OOB check, and may cause OOB for malformed property. Fix by using as OOB check '((index + 1) * sizeof(*ref) > prop->length)'.

[PATCH OLK-6.6] scsi: ufs: mcq: Add NULL check in ufshcd_mcq_abort()

From: Chenyuan Yang <chenyuan0y(a)gmail.com> stable inclusion from stable-v6.6.89 commit d6979fabe812a168d5053e5a41d5a2e9b8afd7bf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC6BWT Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4c324085062919d4e21c69e5e78456dcec0052fe ] A race can occur between the MCQ completion path and the abort handler: once a request completes, __blk_mq_free_request() sets rq->mq_hctx to NULL, meaning the subsequent ufshcd_mcq_req_to_hwq() call in ufshcd_mcq_abort() can return a NULL pointer. If this NULL pointer is dereferenced, the kernel will crash. Add a NULL check for the returned hwq pointer. If hwq is NULL, log an error and return FAILED, preventing a potential NULL-pointer dereference. As suggested by Bart, the ufshcd_cmd_inflight() check is removed. This is similar to the fix in commit 74736103fb41 ("scsi: ufs: core: Fix ufshcd_abort_one racing issue"). This is found by our static analysis tool KNighter.
