Summary

Security update for the Linux Kernel

Details

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

CVE-2020-10135: Legacy pairing and secure-connections pairing authentication in Bluetooth 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).
CVE-2020-10711: A NULL pointer dereference flaw was found in the SELinux subsystem. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmapnetlblimport' routine. This flaw allowed a remote network user to crash the system kernel, resulting in a denial of service (bnc#1171191).
CVE-2020-10751: A flaw was found in the SELinux LSM hook implementation, 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-2019-20812: An issue was discovered in the prbcalcretireblktmo() function in net/packet/afpacket.c can result in a denial of service (CPU consumption and soft lockup) in a certain failure case involving TPACKETV3, aka CID-b43d1f9f7067 (bnc#1172453).
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-2020-0305: In cdevget of chardev.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-2020-12771: btreegccoalesce in drivers/md/bcache/btree.c had a deadlock if a coalescing operation fails (bnc#1171732).
CVE-2020-10773: A kernel stack information leak on s390/s390x was fixed (bnc#1172999).
CVE-2020-14416: A race condition in tty->disc_data handling in the slip and slcan line discipline could lead to a use-after-free, aka CID-0ace17d56824. This affects drivers/net/slip/slip.c and drivers/net/can/slcan.c (bnc#1162002).
CVE-2020-10768: Indirect branch speculation could have been enabled after it was force-disabled by the PRSPECFORCE_DISABLE prctl command. (bnc#1172783).
CVE-2020-10766: Fixed Rogue cross-process SSBD shutdown, where a Linux scheduler logical bug allows an attacker to turn off the SSBD protection. (bnc#1172781).
CVE-2020-10767: Indirect Branch Prediction Barrier was force-disabled when STIBP is unavailable or enhanced IBRS is available. (bnc#1172782).
CVE-2020-13974: drivers/tty/vt/keyboard.c had an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. (bnc#1172775).
CVE-2019-20810: go7007sndinit in drivers/media/usb/go7007/snd-go7007.c in the Linux kernel did not call sndcardfree for a failure path, which causes a memory leak, aka CID-9453264ef586 (bnc#1172458).

The following non-security bugs were fixed:

intel_idle: Graceful probe failure when MWAIT is disabled (bsc#1174115).
x86/dumpstack/64: Handle faults when printing the 'Stack: ' part of an OOPS (bsc#1170383).
xfs: Fix tail rounding in xfsallocfile_space() (bsc#1172049).
