A flaw was found in the Linux kernel in the hid_debug_events_read() function in the drivers/hid/hid-debug.c file. A lack of the certain checks may allow a privileged user ('root') to achieve an out-of-bounds write and thus receiving user space buffer corruption.(CVE-2018-9516)

Note: The Release Date is incorrect. This CVE was fixed July 2018

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001644 advisory.

    In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a     missing bounds check. This could lead to local escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android     ID: A-71361580.

A flaw was found in the Linux kernel in the hid_debug_events_read() function in the drivers/hid/hid-debug.c file. A lack of the certain checks may allow a privileged user ('root') to achieve an out-of-bounds write and thus receiving user space buffer corruption.
(CVE-2018-9516)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2018-6554

A memory leak in the irda_bind function in the irda subsystem was discovered. A local user can take advantage of this flaw to cause a denial of service (memory consumption).

CVE-2018-6555

A flaw was discovered in the irda_setsockopt function in the irda subsystem, allowing a local user to cause a denial of service (use-after-free and system crash).

CVE-2018-7755

Brian Belleville discovered a flaw in the fd_locked_ioctl function in the floppy driver in the Linux kernel. The floppy driver copies a kernel pointer to user memory in response to the FDGETPRM ioctl. A local user with access to a floppy drive device can take advantage of this flaw to discover the location kernel code and data.

CVE-2018-9363

It was discovered that the Bluetooth HIDP implementation did not correctly check the length of received report messages. A paired HIDP device could use this to cause a buffer overflow, leading to denial of service (memory corruption or crash) or potentially remote code execution.

CVE-2018-9516

It was discovered that the HID events interface in debugfs did not correctly limit the length of copies to user buffers. A local user with access to these files could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.
However, by default debugfs is only accessible by the root user.

CVE-2018-10902

It was discovered that the rawmidi kernel driver does not protect against concurrent access which leads to a double-realloc (double free) flaw. A local attacker can take advantage of this issue for privilege escalation.

CVE-2018-10938

Yves Younan from Cisco reported that the Cipso IPv4 module did not correctly check the length of IPv4 options. On custom kernels with CONFIG_NETLABEL enabled, a remote attacker could use this to cause a denial of service (hang).

CVE-2018-13099

Wen Xu from SSLab at Gatech reported a use-after-free bug in the F2FS implementation. An attacker able to mount a crafted F2FS volume could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.

CVE-2018-14609

Wen Xu from SSLab at Gatech reported a potential NULL pointer dereference in the F2FS implementation. An attacker able to mount arbitrary F2FS volumes could use this to cause a denial of service (crash).

CVE-2018-14617

Wen Xu from SSLab at Gatech reported a potential NULL pointer dereference in the HFS+ implementation. An attacker able to mount arbitrary HFS+ volumes could use this to cause a denial of service (crash).

CVE-2018-14633

Vincent Pelletier discovered a stack-based buffer overflow flaw in the chap_server_compute_md5() function in the iSCSI target code. An unauthenticated remote attacker can take advantage of this flaw to cause a denial of service or possibly to get a non-authorized access to data exported by an iSCSI target.

CVE-2018-14678

M. Vefa Bicakci and Andy Lutomirski discovered a flaw in the kernel exit code used on amd64 systems running as Xen PV guests. A local user could use this to cause a denial of service (crash).

CVE-2018-14734

A use-after-free bug was discovered in the InfiniBand communication manager. A local user could use this to cause a denial of service (crash or memory corruption) or possible for privilege escalation.

CVE-2018-15572

Esmaiel Mohammadian Koruyeh, Khaled Khasawneh, Chengyu Song, and Nael Abu-Ghazaleh, from University of California, Riverside, reported a variant of Spectre variant 2, dubbed SpectreRSB. A local user may be able to use this to read sensitive information from processes owned by other users.

CVE-2018-15594

Nadav Amit reported that some indirect function calls used in paravirtualised guests were vulnerable to Spectre variant 2. A local user may be able to use this to read sensitive information from the kernel.

CVE-2018-16276

Jann Horn discovered that the yurex driver did not correctly limit the length of copies to user buffers. A local user with access to a yurex device node could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2018-16658

It was discovered that the cdrom driver does not correctly validate the parameter to the CDROM_DRIVE_STATUS ioctl. A user with access to a cdrom device could use this to read sensitive information from the kernel or to cause a denial of service (crash).

CVE-2018-17182

Jann Horn discovered that the vmacache_flush_all function mishandles sequence number overflows. A local user can take advantage of this flaw to trigger a use-after-free, causing a denial of service (crash or memory corruption) or privilege escalation.

For Debian 8 'Jessie', these problems have been fixed in version 4.9.110-3+deb9u5~deb8u1.

We recommend that you upgrade your linux-4.9 packages.

The SUSE Linux Enterprise 11 SP4 kernel was updated to 3.0.101-108.81 to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-18281: An issue was discovered in the Linux kernel, the mremap() syscall performs TLB flushes after dropping pagetable locks.
If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused (bnc#1113769).

CVE-2018-18710: An issue was discovered in the Linux kernel, an information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751).

CVE-2018-18386: drivers/tty/n_tty.c in the Linux kernel allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825).

CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c in the Linux kernel 4.x allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240).

CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674).

CVE-2017-1000407: An denial of service issue was discovered in the Linux kernel, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021).

CVE-2018-9516: An issue was discovered in the Linux kernel, the copy_to_user() inside the HID code does not correctly check the length before executing (bsc#1108498).

CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host.
Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely (bnc#1107829).

The update package also includes non-security fixes. See advisory for details.

The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.

Four new speculative execution information leak issues have been identified in Intel CPUs. (bsc#1111331)

CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS)

CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS)

CVE-2018-12130: Microarchitectural Load Port Data Samling (MLPDS)

CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM)

This kernel update contains software mitigations for these issues, which also utilize CPU microcode updates shipped in parallel.

For more information on this set of information leaks, check out https://www.suse.com/support/kb/doc/?id=7023736

The following security bugs were fixed: CVE-2016-10741:
fs/xfs/xfs_aops.c allowed local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010).

CVE-2017-1000407: By flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021).

CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674).

CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240).

CVE-2017-7472: The KEYS subsystem allowed local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls (bnc#1034862).

CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host.
Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target.
(bnc#1107829).

CVE-2018-15572: The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517 bnc#1105296).

CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946).

CVE-2018-18281: The mremap() syscall performed TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769).

CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825).

CVE-2018-18690: A local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandled ATTR_REPLACE operations with conversion of an attr from short to long form (bnc#1105025).

CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751).

CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841).

CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).

CVE-2018-19985: The function hso_get_config_data in drivers/net/usb/hso.c read if_num from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds (OOB) read that potentially allowed arbitrary read in the kernel address space (bnc#1120743).

CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714).

CVE-2018-5391: The Linux kernel was vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bnc#1103097).

CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a missing bounds check.
This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
(bnc#1108498).

CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bnc#1118319).

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c had multiple race conditions (bnc#1133188). The line discipline was disabled.

CVE-2019-3459: A heap address information leak while using L2CAP_GET_CONF_OPT was discovered (bnc#1120758).

CVE-2019-3460: A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found (bnc#1120758).

CVE-2019-3882: A flaw was found vfio interface implementation that permitted violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS).
(bnc#1131416 bnc#1131427).

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, leading to a use-after-free (bnc#1124728).

CVE-2019-7221: The KVM implementation had a Use-after-Free (bnc#1124732).

CVE-2019-7222: The KVM implementation had an Information Leak (bnc#1124735).

CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166).

CVE-2019-9503: Multiple brcmfmac frame validation bypasses have been fixed (bnc#1132828).

The update package also includes non-security fixes. See advisory for details.
