Summary

Security update for the Linux Kernel

Details

The SUSE Linux Enterprise 12 SP2 kernel version 4.4.121 was updated to receive various security and bugfixes.

The following security bugs were fixed:

CVE-2019-11477: A sequence of SACKs may have been crafted by a remote attacker such that one can trigger an integer overflow, leading to a kernel panic. (bsc#1137586).
CVE-2019-11478: It was possible to send a crafted sequence of SACKs which would fragment the TCP retransmission queue. A remote attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection.
CVE-2019-11479: It was possible to send a crafted sequence of SACKs which would fragment the RACK send map. A remote attacker may be able to further exploit the fragmented send map to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. This would have resulted in excess resource consumption due to low mss values.
CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bnc#1136424)
CVE-2019-12382: An issue was discovered in drmloadedidfirmware in drivers/gpu/drm/drmedid_load.c in the Linux kernel There is an unchecked kstrdup of fwstr, which may have allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). (bnc#1136586)
CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may have been possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bnc#1120843)
CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might have allowed local users to obtain sensitive information by reading uninitialized data in the filesystem. (bnc#1135281)
CVE-2018-7191: In the tun subsystem in the Linux kernel, devgetvalidname was not called before registernetdevice. This allowed local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to CVE-2013-4343. (bnc#1135603)
CVE-2019-11190: The Linux kernel allowed local users to bypass ASLR on setuid programs (such as /bin/su) because installexeccreds() is called too late in loadelfbinary() in fs/binfmtelf.c, and thus the ptracemay_access() check had a race condition when reading /proc/pid/stat. (bnc#1131543)
CVE-2019-11815: An issue was discovered in rdstcpkill_sock in net/rds/tcp.c in the Linux kernel There was a race condition leading to a use-after-free, related to net namespace cleanup. (bnc#1134537)
CVE-2019-11884: The dohidpsock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not have ended with a '\0' character. (bnc#1134848)
CVE-2018-17972: An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel It did not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. (bnc#1110785)

The following non-security bugs were fixed:

cifs: keep FileInfo handle live during oplock break (bsc#1106284, bsc#1131565).
ftrace/x86_64: Emulate call function while updating in breakpoint handler (bsc#1099658).
kabi: drop LINUXMIBTCPWQUEUETOOBIG snmp counter (bsc#1137586).
kabi: move sysctltcpminsndmss to preserve struct net layout (bsc#1137586).
mwifiex: Fix heap overflow in mwifiexuapparsetailies() (bsc#1136935).
tcp: add tcpminsnd_mss sysctl (bsc#1137586).
tcp: enforce tcpminsndmss in tcpmtu_probing() (bsc#1137586).
tcp: limit payload size of sacked skbs (bsc#1137586).
tcp: tcp_fragment() should apply sane memory limits (bsc#1137586).
x86_64: Add gap to int3 to allow for call emulation (bsc#1099658).
x86_64: Allow breakpoints to emulate call instructions (bsc#1099658).
xen-swiotlb: fix the check condition for xenswiotlbfree_coherent (bnc#1134596).
xen-swiotlb: use actually allocated size on check physical continuous (bnc#1134596).
