The openSUSE Leap 15.2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2019-19462: relay_open in kernel/relay.c allowed local users to cause a denial of service (such as relay blockage) by triggering a NULL alloc_percpu result (bnc#1158265).
• CVE-2019-20810: go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c did not call snd_card_free for a failure path, which causes a memory leak, aka CID-9453264ef586 (bnc#1172458).
• CVE-2019-20812: The prb_calc_retire_blk_tmo() function in net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain failure case involving TPACKET_V3, aka CID-b43d1f9f7067 (bnc#1172453).
• CVE-2020-10711: A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allowed a remote network user to crash the system kernel, resulting in a denial of service (bnc#1171191).
• CVE-2020-10732: A flaw was found in the implementation of Userspace core dumps. This flaw allowed an attacker with a local account to crash a trivial program and exfiltrate private kernel data (bnc#1171220).
• CVE-2020-10751: SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing (bnc#1171189).
• CVE-2020-10766: Fixed rogue cross-process SSBD shutdown. Linux scheduler logical bug allowed an attacker to turn off the SSBD protection. (bnc#1172781).
• CVE-2020-10767: Fixed that Indirect Branch Prediction Barrier is force-disabled when STIBP is unavailable or enhanced IBRS is available. (bnc#1172782).
• CVE-2020-10768: Fixed that indirect branch speculation can be enabled after it was force-disabled by the PR_SPEC_FORCE_DISABLE prctl command (bnc#1172783).
• CVE-2020-10773: Fixed a kernel stack information leak on s390/s390x. (bnc#1172999).
• CVE-2020-12656: Fixed a memory leak in gss_mech_free in the rpcsec_gss_krb5 implementation due to lack of certain domain_release calls (bnc#1171219).
• CVE-2020-12769: An issue was discovered in drivers/spi/spi-dw.c allowed attackers to cause a panic via concurrent calls to dw_spi_irq and dw_spi_transfer_one, aka CID-19b61392c5a8 (bnc#1171983).
• CVE-2020-12888: The VFIO PCI driver mishandled attempts to access disabled memory space (bnc#1171868).
• CVE-2020-13143: gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c relied on kstrdup without considering the possibility of an internal '\0' value, which allowed attackers to trigger an out-of-bounds read, aka CID-15753588bcd4 (bnc#1171982).
• CVE-2020-13974: tty/vt/keyboard.c had an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. (bnc#1172775).

• CVE-2020-0305: In cdev_get of char_dev.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1174462).
• CVE-2020-10135: Legacy pairing and secure-connections pairing authentication in Bluetooth� BR/EDR Core Specification v5.2 and earlier may have allowed an unauthenticated user to complete authentication without pairing credentials via adjacent access. An unauthenticated, adjacent attacker could impersonate a Bluetooth BR/EDR master or slave to pair with a previously paired remote device to successfully complete the authentication procedure without knowing the link key (bnc#1171988).

It was discovered that the XFS file system implementation in the Linux kernel did not properly validate meta data in some circumstances. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service. (CVE-2020-12655)

It was discovered that the bcache subsystem in the Linux kernel did not properly release a lock in some error conditions. A local attacker could possibly use this to cause a denial of service. (CVE-2020-12771)

It was discovered that the Virtual Terminal keyboard driver in the Linux kernel contained an integer overflow. A local attacker could possibly use this to have an unspecified impact. (CVE-2020-13974)

Kyungtae Kim discovered that the USB testing driver in the Linux kernel did not properly deallocate memory on disconnect events. A physically proximate attacker could use this to cause a denial of service (memory exhaustion). (CVE-2020-15393)

It was discovered that the NFS server implementation in the Linux kernel did not properly honor umask settings when setting permissions while creating file system objects if the underlying file system did not support ACLs. An attacker could possibly use this to expose sensitive information or violate system integrity. (CVE-2020-24394)

It was discovered that the Kerberos SUNRPC GSS implementation in the Linux kernel did not properly deallocate memory on module unload. A local privileged attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2020-12656)
