[PATCH openEuler-1.0-LTS] ALSA: rawmidi: Fix racy buffer resize under concurrent accesses
by Yang Yingliang 08 Jan '21

08 Jan '21

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from linux-4.19.124 commit a507658fdb2ad8ca282b0eb42f2a40b805deb1e6 CVE: CVE-2020-27786 -------------------------------- commit c1f6e3c818dd734c30f6a7eeebf232ba2cf3181d upstream. The rawmidi core allows user to resize the runtime buffer via ioctl, and this may lead to UAF when performed during concurrent reads or writes: the read/write functions unlock the runtime lock temporarily during copying form/to user-space, and that's the race window. This patch fixes the hole by introducing a reference counter for the runtime buffer read/write access and returns -EBUSY error when the resize is performed concurrently against read/write. Note that the ref count field is a simple integer instead of refcount_t here, since the all contexts accessing the buffer is basically protected with a spinlock, hence we need no expensive atomic ops. Also, note that this busy check is needed only against read / write functions, and not in receive/transmit callbacks; the race can happen only at the spinlock hole mentioned in the above, while the whole function is protected for receive / transmit callbacks.

[PATCH 01/10] vfio: allow external user to get vfio group from device
by Yang Yingliang 04 Jan '21

04 Jan '21

From: Yan Zhao <yan.y.zhao(a)intel.com> mainline inclusion from mainline-v5.6-rc7 commit c0560f51cf77472f4ed113539b0a02ca6cda7961 category: Common features bugzilla: 46841 CVE: NA ------------------------------------------------- external user calls vfio_group_get_external_user_from_dev() with a device pointer to get the VFIO group associated with this device. The VFIO group is checked to be vialbe and have IOMMU set. Then container user counter is increased and VFIO group reference is hold to prevent the VFIO group from disposal before external user exits. when the external user finishes using of the VFIO group, it calls vfio_group_put_external_user() to dereference the VFIO group and the container user counter.
