CVE-2020-13143: Fixed an out-of-bounds read in gadget_dev_desc_UDC_store
 in drivers/usb/gadget/configfs.c (bsc#1171982).

CVE-2020-12769: Fixed an issue which could have allowed attackers to
 cause a panic via concurrent calls to dw_spi_irq and dw_spi_transfer_one
 (bsc#1171983).

CVE-2020-12768: Fixed a memory leak in svm_cpu_uninit in
 arch/x86/kvm/svm.c (bsc#1171736).

CVE-2020-12659: Fixed an out-of-bounds write (by a user with the
 CAP_NET_ADMIN capability) due to improper headroom validation

CVE-2020-12656: Fixed an improper handling of certain domain_release
 calls leadingch could have led to a memory leak (bsc#1171219).

CVE-2020-12655: Fixed an issue which could have allowed attackers to
 trigger a sync of excessive duration via an XFS v5 image with crafted
 metadata (bsc#1171217).

 allowed local users to gain privileges or cause a denial of service
 (bsc#1171195).

CVE-2020-12652: Fixed an issue which could have allowed local users to
 hold an incorrect lock during the ioctl operation and trigger a race
 condition (bsc#1171218).

CVE-2020-12464: Fixed a use-after-free due to a transfer without a
 reference (bsc#1170901).

CVE-2020-12114: Fixed a pivot_root race condition which could have
 allowed local users to cause a denial of service (panic) by corrupting a
 mountpoint reference counter (bsc#1171098).

 (bsc#1170778).

CVE-2020-10711: Fixed a null pointer dereference in SELinux subsystem
 which could have allowed a remote network user to crash the kernel
 resulting in a denial of service (bsc#1171191).

CVE-2020-10690: Fixed the race between the release of ptp_clock and cdev
 (bsc#1170056).

CVE-2019-9455: Fixed a pointer leak due to a WARN_ON statement in a
 video driver. This could lead to local ... [Please see the references for more information on the vulnerabilities]");
