Description

The openSUSE 14.2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

  • CVE-2016-9576: A use-after-free vulnerability in the SCSI generic driver allows users with write access to /dev/sg or /dev/bsg to elevate their privileges (bsc#1013604).

The following non-security bugs were fixed :

  • 8250_pci: Fix potential use-after-free in error path (bsc#1013001).

  • block_dev: do not test bdev->bd_contains when it is not stable (bsc#1008557).

  • drm/i915/vlv: Disable HPD in valleyview_crt_detect_hotplug() (bsc#1014120).

  • drm/i915/vlv: Make intel_crt_reset() per-encoder (bsc#1014120).

  • drm/i915/vlv: Reset the ADPA in vlv_display_power_well_init() (bsc#1014120).

  • drm/i915: Enable polling when we do not have hpd (bsc#1014120).

  • i2c: designware-baytrail: Add support for cherrytrail (bsc#1011913).

  • i2c: designware-baytrail: Pass dw_i2c_dev into helper functions (bsc#1011913).

  • i2c: designware: Prevent runtime suspend during adapter registration (bsc#1011913).

  • i2c: designware: Use transfer timeout from ioctl I2C_TIMEOUT (bsc#1011913).

  • i2c: designware: retry transfer on transient failure (bsc#1011913).

  • powerpc/xmon: Add xmon command to dump process/task similar to ps(1) (fate#322020).

  • sched/fair: Fix incorrect task group ->load_avg (bsc#981825).

  • serial: 8250_pci: Detach low-level driver during PCI error recovery (bsc#1013001).

  • target: fix tcm_rbd_gen_it_nexus for emulated XCOPY state (bsc#1003606).

  • x86/PCI: VMD: Synchronize with RCU freeing MSI IRQ descs (bsc#1006827).
