[PATCH openEuler-1.0-LTS 1/6] crypto: ecdh - avoid unaligned accesses in ecdh_set_secret()
by Yongqiang Liu 11 Jan '23

11 Jan '23

From: Ard Biesheuvel <ardb(a)kernel.org> stable inclusion from stable-v4.19.164 commit 85637bc064f4fd5539d4173798d8cb55dde7fc0a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I65ZD2 CVE: NA -------------------------------- commit 17858b140bf49961b71d4e73f1c3ea9bc8e7dda0 upstream. ecdh_set_secret() casts a void* pointer to a const u64* in order to feed it into ecc_is_key_valid(). This is not generally permitted by the C standard, and leads to actual misalignment faults on ARMv6 cores. In some cases, these are fixed up in software, but this still leads to performance hits that are entirely avoidable. So let's copy the key into the ctx buffer first, which we will do anyway in the common case, and which guarantees correct alignment.

[PATCH openEuler-1.0-LTS 1/8] mm/hwpoison: do not lock page again when me_huge_page() successfully recovers
by Yongqiang Liu 11 Jan '23

11 Jan '23

From: Naoya Horiguchi <naoya.horiguchi(a)nec.com> mainline inclusion from mainline-v5.13 commit ea6d0630100b285f059d0a8d8e86f38a46407536 category: bugfix bugzilla: 188222, https://gitee.com/openeuler/kernel/issues/I69SHF CVE: NA -------------------------------- Currently me_huge_page() temporary unlocks page to perform some actions then locks it again later. My testcase (which calls hard-offline on some tail page in a hugetlb, then accesses the address of the hugetlb range) showed that page allocation code detects this page lock on buddy page and printed out "BUG: Bad page state" message. check_new_page_bad() does not consider a page with __PG_HWPOISON as bad page, so this flag works as kind of filter, but this filtering doesn't work in this case because the "bad page" is not the actual hwpoisoned page. So stop locking page again. Actions to be taken depend on the page type of the error, so page unlocking should be done in ->action() callbacks. So let's make it assumed and change all existing callbacks that way.

[PATCH openEuler-5.10-LTS 1/9] xfs: get rid of assert from xfs_btree_islastblock
by Zheng Zengkai 06 Jan '23

06 Jan '23

From: Guo Xuenan <guoxuenan(a)huawei.com> mainline inclusion from mainline-v6.1-rc4 commit 8c25febf23963431686f04874b96321288504127 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4KIAO CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- xfs_btree_check_block contains debugging knobs. With XFS_DEBUG setting up, turn on the debugging knob can trigger the assert of xfs_btree_islastblock, test script as follows: while true do mount $disk $mountpoint fsstress -d $testdir -l 0 -n 10000 -p 4 >/dev/null echo 1 > /sys/fs/xfs/sda/errortag/btree_chk_sblk sleep 10 umount $mountpoint done Kick off fsstress and only *then* turn on the debugging knob. If it happens that the knob gets turned on after the cntbt lookup succeeds but before the call to xfs_btree_islastblock, then we *can* end up in the situation where a previously checked btree block suddenly starts returning EFSCORRUPTED from xfs_btree_check_block. Kaboom. Darrick give a very detailed explanation as follows: Looking back at commit 27d9ee577dcce, I think the point of all this was to make sure that the cursor has actually performed a lookup, and that the btree block at whatever level we're asking about is ok. If the caller hasn't ever done a lookup, the bc_levels array will be empty, so cur->bc_levels[level].bp pointer will be NULL. The call to xfs_btree_get_block will crash anyway, so the "ASSERT(block);" part is pointless. If the caller did a lookup but the lookup failed due to block corruption, the corresponding cur->bc_levels[level].bp pointer will also be NULL, and we'll still crash. The "ASSERT(xfs_btree_check_block);" logic is also unnecessary. If the cursor level points to an inode root, the block buffer will be incore, so it had better always be consistent. If the caller ignores a failed lookup after a successful one and calls this function, the cursor state is garbage and the assert wouldn't have tripped anyway. So get rid of the assert.

The call chain can be gru_unload_context->gru_free_gru_context->gts_drop and kfree finally. However, the caller didn't know if the gts is freed or not and use it afterwards. This will trigger a Use after Free bug. Fix it by introducing a return value to see if it's in error path or not. Free the gts in caller if gru_check_chiplet_assignment check failed.

[PATCH openEuler-5.10-LTS] wifi: wilc1000: validate length of IEEE80211_P2P_ATTR_CHANNEL_LIST attribute

From: Phil Turnbull <philipturnbull(a)github.com> stable inclusion from stable-v5.10.157 commit 5a068535c0073c8402aa0755e8ef259fb98a33c5 category: bugfix bugzilla: 188173 https://gitee.com/src-openeuler/kernel/issues/I66M3J CVE: CVE-2022-47521 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f9b62f9843c7b0afdaecabbcebf1dbba18599408 upstream. Validate that the IEEE80211_P2P_ATTR_CHANNEL_LIST attribute contains enough space for a 'struct wilc_attr_oper_ch'. If the attribute is too small then it can trigger an out-of-bounds write later in the function. 'struct wilc_attr_oper_ch' is variable sized so also check 'attr_len' does not extend beyond the end of 'buf'.

[PATCH openEuler-1.0-LTS] media: dvb-core: Fix UAF due to refcount races at releasing
by Yongqiang Liu 24 Dec '22

24 Dec '22

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.1.1 commit fd3d91ab1c6ab0628fe642dd570b56302c30a792 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5SDE4 CVE: CVE-2022-41218 -------------------------------- The dvb-core tries to sync the releases of opened files at dvb_dmxdev_release() with two refcounts: dvbdev->users and dvr_dvbdev->users. A problem is present in those two syncs: when yet another dvb_demux_open() is called during those sync waits, dvb_demux_open() continues to process even if the device is being closed. This includes the increment of the former refcount, resulting in the leftover refcount after the sync of the latter refcount at dvb_dmxdev_release(). It ends up with use-after-free, since the function believes that all usages were gone and releases the resources. This patch addresses the problem by adding the check of dmxdev->exit flag at dvb_demux_open(), just like dvb_dvr_open() already does. With the exit flag check, the second call of dvb_demux_open() fails, hence the further corruption can be avoided. Also for avoiding the races of the dmxdev->exit flag reference, this patch serializes the dmxdev->exit set up and the sync waits with the dmxdev->mutex lock at dvb_dmxdev_release(). Without the mutex lock, dvb_demux_open() (or dvb_dvr_open()) may run concurrently with dvb_dmxdev_release(), which allows to skip the exit flag check and continue the open process that is being closed. CVE-2022-41218 is assigned to those bugs above.

[PATCH openEuler-1.0-LTS 1/4] Bluetooth: L2CAP: Fix use-after-free caused by l2cap_chan_put

From: Luiz Augusto von Dentz <luiz.von.dentz(a)intel.com> stable inclusion from stable-v4.19.255 commit d0be8347c623e0ac4202a1d4e0373882821f56b0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I64WCC CVE: CVE-2022-20566 -------------------------------- commit d0be8347c623e0ac4202a1d4e0373882821f56b0 upstream. This fixes the following trace which is caused by hci_rx_work starting up *after* the final channel reference has been put() during sock_close() but *before* the references to the channel have been destroyed, so instead the code now rely on kref_get_unless_zero/l2cap_chan_hold_unless_zero to prevent referencing a channel that is about to be destroyed. refcount_t: increment on 0; use-after-free.

[PATCH openEuler-1.0-LTS 1/3] xen/netback: Ensure protocol headers don't fall in the non-linear area
by Yongqiang Liu 16 Dec '22

16 Dec '22

From: Ross Lagerwall <ross.lagerwall(a)citrix.com> mainline inclusion from mainline-v6.1 commit ad7f402ae4f466647c3a669b8a6f3e5d4271c84a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I651EB CVE: CVE-2022-3643 -------------------------------- In some cases, the frontend may send a packet where the protocol headers are spread across multiple slots. This would result in netback creating an skb where the protocol headers spill over into the non-linear area. Some drivers and NICs don't handle this properly resulting in an interface reset or worse. This issue was introduced by the removal of an unconditional skb pull in the tx path to improve performance. Fix this without reintroducing the pull by setting up grant copy ops for as many slots as needed to reach the XEN_NETBACK_TX_COPY_LEN size. Adjust the rest of the code to handle multiple copy operations per skb. This is XSA-423 / CVE-2022-3643.

[PATCH openEuler-1.0-LTS] arm64: fix a concurrency issue in emulation_proc_handler()
by Yongqiang Liu 16 Dec '22

16 Dec '22

From: ruanjinjie <ruanjinjie(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I65T0J CVE: NA ------------------------------- In emulation_proc_handler(), read and write operations are performed on insn->current_mode. In the concurrency scenario, mutex only protects writing insn->current_mode, and not protects the read. Suppose there are two concurrent tasks, task1 updates insn->current_mode to INSN_EMULATE in the critical section, the prev_mode of task2 is still the old data INSN_UNDEF of insn->current_mode. As a result, two tasks call update_insn_emulation_mode twice with prev_mode = INSN_UNDEF and current_mode = INSN_EMULATE, then call register_emulation_hooks twice, resulting in a list_add double problem.

[PATCH openEuler-5.10-LTS 01/23] mm/dynamic_hugetlb: fix compound_nr incorrect

13 Dec '22

From: Liu Shixin <liushixin2(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I641XX CVE: NA -------------------------------- Patch 1378a5ee451a ("mm: store compound_nr as well as compound_order") add a new member compound_nr in struct page, and use this new member insteal of compound_order in hugetlb_cgroup_move_parent() to compute the nr_pages. In free_hugepage_to_hugetlb(), we reset page->mapping to NULL for each subpage. Since page->mapping and page->compound_nr is union, we reset page->compound_nr too unexpectly. This will finally result the nr_pages incorrect in hugetlb_cgroup_move_parent() and can't release hugetlb_cgroup. Fix this problem by reset page->compound_nr using set_compound_order().

[PATCH openEuler-1.0-LTS 1/3] USB: add usb_control_msg_send() and usb_control_msg_recv()
by Yongqiang Liu 13 Dec '22

13 Dec '22

From: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> mainline inclusion from mainline-v5.10-rc1 commit 719b8f2850d3d9b863cc5e4f08e9ef0206e45b26 category: bugfix bugzilla: 188090, https://gitee.com/src-openeuler/kernel/issues/I6068W CVE: CVE-2022-3903 -------------------------------- New core functions to make sending/receiving USB control messages easier and saner. In discussions, it turns out that the large majority of users of usb_control_msg() do so in potentially incorrect ways. The most common issue is where a "short" message is received, yet never detected properly due to "incorrect" error handling. Handle all of this in the USB core with two new functions to try to make working with USB control messages simpler. No more need for dynamic data, messages can be on the stack, and only "complete" send/receive will work without causing an error. Link: https://lore.kernel.org/r/20200914153756.3412156-3-gregkh@linuxfoundation.o… Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> The parts related to usb_control_msg_send() and usb_control_msg_recv() in commit USB: correct API of usb_control_msg_send/recv are added to solve CVE. Commit USB: core: drop pipe-type check from new control-message helpers is also added.
