CPU1 starts to process it. A work 'aer_isr()' is scheduled on CPU1. It calling into pcie_do_fatal_recovery(), and aquire lock 'pci_rescan_remove_lock'. Before it removes the sysfs corresponding to the error pci device, a sysfs remove operation is executed on CPU0. CPU0 use device_remove_file_self() to remove the sysfs directory and wait for the lock to be released. After CPU1 finish pci_stop_and_remove_bus_device(), it release the lock and free the 'pci_dev' in pci_dev_put(). CPU0 acquire the lock and access the 'pci_dev'. Then a use-after-free is triggered. To fix this issue, we increase the reference count in remove_store() before remove the device and decrease the reference count in the end.

[PATCH OLK-5.10] usb: gadget: rndis: Fix info leak of rndis
by Zheng Zengkai 22 Jul '21

22 Jul '21

From: Wang Hai <wanghai38(a)huawei.com> hulk inclusion category: bugfix bugzilla: 172330 CVE: HWPSIRT-2021-84477 -------------------------------- We can construct some special USB packets that cause kernel info leak by the following steps of rndis. 1. construct the packet to make rndis call gen_ndis_set_resp(). In gen_ndis_set_resp(), BufOffset comes from the USB packet and it is not checked so that BufOffset can be any value. Therefore, if OID is RNDIS_OID_GEN_CURRENT_PACKET_FILTER, then *params->filter can get data at any address. 2. construct the packet to make rndis call rndis_query_response(). In rndis_query_response(), if OID is RNDIS_OID_GEN_CURRENT_PACKET_FILTER, then the data of *params->filter is fetched and returned, resulting in info leak. Therefore, we need to check the BufOffset to prevent info leak. Here, buf size is USB_COMP_EP0_BUFSIZ, as long as "8 + BufOffset + BufLength" is less than USB_COMP_EP0_BUFSIZ, it will be considered legal.

[PATCH kernel-4.19] mm: slab: fix kmem_cache_create failed when sysfs node not destroyed
by Yang Yingliang 21 Jul '21

21 Jul '21

From: Nanyong Sun <sunnanyong(a)huawei.com> hulk inclusion category: bugfix bugzilla: 174641 CVE: NA ------------------------------------ The commit d38a2b7a9c93 ("mm: memcg/slab: fix memory leak at non-root kmem_cache destroy") introduced a problem: If one thread destroy a kmem_cache A and another thread concurrently create a kmem_cache B, which is mergeable with A and has same size with A, the B may fail to create due to the duplicate sysfs node. The scenario in detail: 1) Thread 1 uses kmem_cache_destroy() to destroy kmem_cache A which is mergeable, it decreases A's refcount and if refcount is 0, then call memcg_set_kmem_cache_dying() which set A->memcg_params.dying = true, then unlock the slab_mutex and call flush_memcg_workqueue(), it may cost a while. Note: now the sysfs node(like '/kernel/slab/:0000248') of A is still present, it will be deleted in shutdown_cache() which will be called after flush_memcg_workqueue() is done and lock the slab_mutex again. 2) Now if thread 2 is coming, it use kmem_cache_create() to create B, which is mergeable with A(their size is same), it gain the lock of slab_mutex, then call __kmem_cache_alias() trying to find a mergeable node, because of the below added code in commit d38a2b7a9c93 ("mm: memcg/slab: fix memory leak at non-root kmem_cache destroy"), B is not mergeable with A whose memcg_params.dying is true. int slab_unmergeable(struct kmem_cache *s) if (s->refcount < 0) return 1; /* * Skip the dying kmem_cache. */ if (s->memcg_params.dying) return 1; return 0; } So B has to create its own sysfs node by calling: create_cache-> __kmem_cache_create-> sysfs_slab_add-> kobject_init_and_add Because B is mergeable itself, its filename of sysfs node is based on its size, like '/kernel/slab/:0000248', which is duplicate with A, and the sysfs node of A is still present now, so kobject_init_and_add() will return fail and result in kmem_cache_create() fail. Concurrently modprobe and rmmod the two modules below can reproduce the issue quickly: nf_conntrack_expect, se_sess_cache. See call trace in the end. LTS versions of v4.19.y and v5.4.y have this problem, whereas linux versions after v5.9 do not have this problem because the patchset: ("The new cgroup slab memory controller") almost refactored memcg slab. A potential solution(this patch belongs): Just let the dying kmem_cache be mergeable, the slab_mutex lock can prevent the race between alias kmem_cache creating thread and root kmem_cache destroying thread. In the destroying thread, after flush_memcg_workqueue() is done, judge the refcount again, if someone reference it again during un-lock time, we don't need to destroy the kmem_cache completely, we can reuse it. Another potential solution: revert the commit d38a2b7a9c93 ("mm: memcg/slab: fix memory leak at non-root kmem_cache destroy"), compare to the fail of kmem_cache_create, the memory leak in special scenario seems less harmful.
