An update that solves 28 vulnerabilities and has 20 fixes is now available.

Description:

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls (bsc#1167629).
  • CVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bsc#1162929).
  • CVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bsc#1162931).
  • CVE-2020-9383: An issue was discovered set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it (bsc#1165111).
  • CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bsc#1159285).
  • CVE-2020-11608: Fixed a NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints (bsc#1168829).
  • CVE-2020-8648: There was a use-after-free vulnerability in the n_tty_receive_buf_common function in drivers/tty/n_tty.c (bsc#1162928).
  • CVE-2019-14896: A heap-based buffer overflow vulnerability was found in Marvell WiFi chip driver. A remote attacker could cause a denial of service or possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP (bsc#1157157).
  • CVE-2019-14897: A stack-based buffer overflow was found in the Marvell WiFi chip driver. An attacker is able to cause a denial of service or possibly execute arbitrary code, when a STA works in IBSS mode and connects to another STA (bsc#1157155).
  • CVE-2019-18675: Fixed an Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allowed local users to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation (bsc#1157804).
  • CVE-2019-19965: Fixed a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition (bsc#1159911).
  • CVE-2019-19066: A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c allowed attackers to cause a denial of service by triggering bfa_port_get_stats() failures (bsc#1157303).
  • CVE-2019-20096: Fixed a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service (bsc#1159908).
  • CVE-2019-19966: Fixed a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service (bsc#1159841).
  • CVE-2019-19532: Fixed multiple out-of-bounds write bugs that can be caused by a malicious USB device (bsc#1158824).
  • CVE-2019-19523: Fixed a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/adutux.c driver (bsc#115882).
  • CVE-2019-19537: Fixed a race condition that can be caused by a malicious USB device in the USB character device driver layer (bsc#1158904).
  • CVE-2019-19527, CVE-2019-19530, CVE-2019-19524: Fixed multiple use-after-free bug that could be caused by a malicious USB device (bsc#1158381, bsc#1158834, bsc#1158900).
  • CVE-2019-15213: Fixed a use-after-free caused by a malicious USB device in the drivers/media/usb/dvb-usb/dvb-usb-init.c driver (bsc#1146544).
  • CVE-2019-19531: Fixed a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/yurex.c driver (bsc#1158445).
  • CVE-2019-18660: The Linux kernel on powerpc allowed Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs (bsc#1157038).
  • CVE-2019-19227: Fixed a potential NULL pointer dereference in the AppleTalk subsystem (bsc#1157678).
  • CVE-2019-19074: Fixed a memory leak in the ath9k_wmi_cmd(), which allowed attackers to cause a denial of service (bsc#1157143).
  • CVE-2019-19073: Fixed multiple memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c, which allowed attackers to cause a denial of service (bsc#1157070).
  • CVE-2019-15916: Fixed a memory leak in register_queue_kobjects() in net/core/net-sysfs.c, which could cause denial of service (bsc#1149448).
