| Title: | Security update for the Linux Kernel (Important) |
| Description: |
The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2020-0543: Fixed a side channel attack against special registers which could have resulted in leaking of read values to cores other than the one which called it. This attack is known as Special Register Buffer Data Sampling (SRBDS) or 'CrossTalk' (bsc#1154824). - 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-2020-12653: Fixed an issue in the wifi driver which could have allowed local users to gain privileges or cause a denial of service (bsc#1171195). - CVE-2020-12654: Fixed an issue in he wifi driver which could have allowed a remote AP to trigger a heap-based buffer overflow (bsc#1171202). - CVE-2020-12656: Fixed an improper handling of certain domain_release calls leadingch could have led to a memory leak (bsc#1171219). - 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). - CVE-2020-10757: Fixed an issue where remaping hugepage DAX to anon mmap could have caused user PTE access (bsc#1172317).
The following non-security bugs were fixed:
- can, slip: Protect tty->disc_data in write_wakeup and close with RCU (bsc#1171698). - clocksource/drivers/hyper-v: Set TSC clocksource as default w/ InvariantTSC (bsc#1170620). - Drivers: HV: Send one page worth of kmsg dump over Hyper-V during panic (bsc#1170618). - Drivers: hv: vmbus: Fix the issue with freeing up hv_ctl_table_hdr (bsc#1170618). - Drivers: hv: vmbus: Get rid of MSR access from vmbus_drv.c (bsc#1170618). - Drivers: hv: vmbus: Make panic reporting to be more useful (bsc#1170618). - Drivers: hv: vmus: Fix the check for return value from kmsg get dump buffer (bsc#1170618). - EDAC: Convert to new X86 CPU match macros - ibmvfc: do not send implicit logouts prior to NPIV login (bsc#1169625 ltc#184611). - ibmvfc: Fix NULL return compiler warning (bsc#1161951 ltc#183551). - KEYS: reaching the keys quotas correctly (bsc#1171689). - NFS: Cleanup if nfs_match_client is interrupted (bsc#1169025). - NFS: Fix a double unlock from nfs_match,get_client (bsc#1169025). - NFS: make nfs_match_client killable (bsc#1169025). - NFS: Unlock requests must never fail (bsc#1172032). - random: always use batched entropy for get_random_u{32,64} (bsc#1164871). - Revert 'ipc,sem: remove uneeded sem_undo_list lock usage in exit_sem()' (bsc#1172221). - scsi: ibmvfc: Avoid loss of all paths during SVC node reboot (bsc#1161951 ltc#183551). - scsi: ibmvfc: Fix NULL return compiler warning (bsc#1161951 ltc#183551). - x86/dumpstack/64: Handle faults when printing the 'Stack: ' part of an OOPS (bsc#1170383). - x86/hyperv: Allow guests to enable InvariantTSC (bsc#1170620). - x86/Hyper-V: Free hv_panic_page when fail to register kmsg dump (bsc#1170618). - x86/Hyper-V: Report crash data in die() when panic_on_oops is set (bsc#1170618). - x86/Hyper-V: Report crash register data or kmsg before running crash kernel (bsc#1170618). - x86/Hyper-V: Report crash register data when sysctl_record_panic_msg is not set (bsc#1170618). - x86: hyperv: report value of misc_features (git fixes). - x86/Hyper-V: Trigger crash enlightenment only once during system crash (bsc#1170618). - x86/Hyper-V: Unload vmbus channel in hv panic callback (bsc#1170618).
