| CVE-2026-105390 | 1 Openvpn | 1 Ovpn-dco-win | 2026-10-23 | N/A |
| Improper synchronization in the OpenVPN ovpn-dco-win for Windows versions 0.6.5 through 1.3.5 and 2.4.0 through 2.8.7 allows local attackers to trigger a deadlock via a crafted write to the ovpn-dco device, causing the host to become unresponsive. | ||||
| CVE-2026-99061 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: fix P2P device removal race in brcmf_detach() When the driver is removed while the user space process that created the P2P device (e.g. wpa_supplicant) is still exiting, the P2P device interface is removed twice and the kernel crashes. The two paths are: - wpa_supplicant, on exit, sends NL80211_CMD_DEL_INTERFACE for the P2P device. nl80211_del_interface() holds RTNL and the wiphy mutex and calls brcmf_p2p_del_vif(), which disables discovery and waits up to 1.5 s for BRCMF_E_IF_DEL. Then it calls brcmf_remove_interface(), which unregisters the wdev and frees the vif and the ifp. - brcmf_detach() sets the bus down, so BRCMF_E_IF_DEL never arrives, and calls brcmf_remove_interface(ifp, false) for the same ifp. brcmf_p2p_ifp_removed() reads ifp->vif and then blocks on rtnl_lock(). When brcmf_p2p_del_vif() releases RTNL, it calls cfg80211_unregister_wdev() on the wdev that was already unregistered and freed. The second list_del_rcu() of wdev->list faults on LIST_POISON2: brcmfmac: brcmf_p2p_del_vif delete P2P vif brcmfmac: brcmf_p2p_deinit_discovery enter brcmfmac: brcmf_p2p_del_vif P2P: GO_NEG_PHASE status cleared brcmfmac: brcmf_detach Enter brcmfmac: brcmf_bus_change_state 1 -> 0 brcmfmac: brcmf_remove_interface Enter, bsscfgidx=1, ifidx=0 brcmfmac: brcmf_del_if Enter, bsscfgidx=1, ifidx=0 brcmfmac: brcmf_p2p_ifp_removed P2P: device interface removed [1.5 s later, brcmf_p2p_del_vif() timed out] brcmfmac: brcmf_remove_interface Enter, bsscfgidx=1, ifidx=0 brcmfmac: brcmf_del_if Enter, bsscfgidx=1, ifidx=0 brcmfmac: brcmf_p2p_ifp_removed P2P: device interface removed Unable to handle kernel paging request at virtual address dead000000000122 Internal error: Oops: 96000044 [#1] PREEMPT_RT SMP pc : _cfg80211_unregister_wdev+0x6c/0x264 [cfg80211] Call trace: _cfg80211_unregister_wdev+0x6c/0x264 [cfg80211] cfg80211_unregister_wdev+0x10/0x1c [cfg80211] brcmf_p2p_ifp_removed+0x84/0xb0 [brcmfmac] brcmf_remove_interface+0x1f4/0x254 [brcmfmac] brcmf_detach+0x88/0x180 [brcmfmac] brcmf_sdio_remove+0x90/0x7b0 [brcmfmac] brcmf_sdiod_remove+0x20/0xa0 [brcmfmac] brcmf_ops_sdio_remove+0xbc/0x12c [brcmfmac] sdio_bus_remove+0x38/0x144 device_release_driver_internal+0x1e8/0x2c0 device_release_driver+0x14/0x20 brcmf_sdio_bus_remove+0x2c/0x40 [brcmfmac] brcmf_fwvid_unregister_vendor+0xd8/0x170 [brcmfmac] __exit_compat+0x18/0x418 [brcmfmac_cyw] __arm64_sys_delete_module+0x1ac/0x244 The log was taken with debug=0x406 on an i.MX 8M Plus board with a CYW55513 (Sona IF513) on SDIO. The driver is the Ezurio backport of brcmfmac from v6.18.22 on a 5.4-rt kernel. The code involved is the same in mainline. To reproduce: 1. Start wpa_supplicant on wlan0 and let it associate. It creates the P2P device (iw dev shows "type P2P-device"). 2. Stop wpa_supplicant and remove the driver without waiting for wpa_supplicant to exit: kill $(pidof wpa_supplicant) rmmod brcmfmac_cyw brcmfmac The crash is reproducible on that board. For the interface without a netdev (the P2P device), take RTNL and the wiphy mutex in brcmf_detach() before reading iflist, and remove it with locked=true. If brcmf_p2p_del_vif() runs first, brcmf_detach() finds the slot empty. If brcmf_detach() runs first, nl80211 does not find the wdev any more. The interfaces with a netdev are removed as before, because brcmf_del_if() takes RTNL on its own for the primary interface. | ||||

| CVE-2026-98994 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: statmount: read the parent of an unmounted mount under mount_lock statmount_mnt_basic() reads the ids of the parent through m->mnt_parent with namespace_sem held for reading. That's fine for a mount that is in a namespace. Everything above it is pinned by that namespace. STATMOUNT_BY_FD also accepts a file descriptor on a mount that has been unmounted on purpose and that only the file descriptor keeps alive. If that mount stayed attached to its parent when it was unmounted the parent is unmounted as well and nothing pins it for the child. The final mntput() unmounts the children under mount_lock alone and frees the parent afterwards. Concurrently, statmount_mnt_basic() reads m->mnt_parent twice while that can happen and can easily dereference a mount that's already gone. Read the parent of an unmounted mount under mount_lock. The parent can't be put while it is held and both ids come from the same mount. A mounted mount's parent is pinned by the namespace and a mount can't leave its namespace while namespace_sem is held, so the common case takes no global lock. | ||||

| CVE-2026-99035 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: mmc: mtk-sd: Cancel request timeout work on remove The driver queues req_timeout while a request is active. msdc_request_done() uses cancel_delayed_work(), which does not wait for a timeout callback that has already started. The timeout callback calls mmc_request_done(), which wakes the request waiter, and then continues to use host->dev_comp and check the SDIO IRQ. During unbind, msdc_drv_remove() can return and the managed mmc_host can be freed before the callback finishes. KASAN reported use-after-free accesses in msdc_request_done() and msdc_recheck_sdio_irq() in each of three unbind tests. The same tests completed without a kernel diagnostic after this change. Call cancel_delayed_work_sync() after mmc_remove_host() has stopped new requests and before the driver releases the host resources. | ||||
| CVE-2026-99036 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: dm: fix reading free memory in do_resume When do_resume calls dm_table_get_mode(new_map), the call is done without holding any locks (it only holds a reference to the md). It may be possible that another concurrent ioctl on the same device will swap table after dm_swap_table and before dm_table_get_mode. In this case, dm_table_get_mode(new_map) reads freed memory. This race condition was triggered by syzbot. This commit fixes the race by reading mode of the new table before dm_swap_table. Note that new_map is also passed to dm_ima_need_measure, but this function doesn't attempt to dereference it, so this call should be safe. Note that this is not a security bug because only root can trigger it and the commonly used tools such as lvm or cryptsetup do not call the ioctls concurrently, so that they can't trigger it acceidentally. | ||||

| CVE-2026-99001 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/xe/i2c: cancel the client work on remove xe_i2c_notifier() stores the DesignWare adapter in i2c->adapter and schedules i2c->work when the adapter is registered under the xe I2C platform device, and xe_i2c_client_work() then instantiates the AMC client device on that adapter. xe_i2c_remove() tears down the AMC, unregisters the client devices, the bus notifier and the adapter platform device, but it never drains i2c->work. A work item that is still queued or running when the adapter is unregistered dereferences i2c->adapter in i2c_new_client_device() after platform_device_unregister() has released the adapter. The work item is also embedded in the devm-allocated struct xe_i2c, so a work item still queued after the drm device devm unwind frees that allocation runs its callback on freed memory. The bus notifier is the only thing that schedules this work, and it is unregistered after the client devices. An instance that is still queued when the teardown runs can therefore write i2c->client[XE_I2C_CLIENT_AMC] while the loop is unregistering and clearing the same array, and an AMC client it instantiates late is only cleaned up by the adapter's own child sweep in i2c_del_adapter(). Move bus_unregister_notifier() in front of the client teardown loop and cancel the work right after it, so no new instance can be scheduled and a queued instance is drained before the client array is touched. A running instance still finds a live adapter, since the adapter is unregistered later. (cherry picked from commit a23f27d5ec11c3f418c5e5531eea34ccda2b5b20) | ||||
