CVE-2017-13695

The acpi_ns_evaluate() function in drivers/acpi/acpica/nseval.c in the Linux kernel through 4.12.9 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.

acpi operand cache leak in dsutils.c (CVE-2017-13693).

acpi parse and parseext cache leaks (CVE-2017-13694).

acpi operand cache leak in nseval.c (CVE-2017-13695).

The SUSE Linux Enterprise 12 SP2 kernel was updated.

The following security bugs were fixed:

• CVE-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c vulnerability in the Linux kernel (bnc#1198031).
• CVE-2022-28388: Fixed a double free in drivers/net/can/usb/usb_8dev.c vulnerability in the Linux kernel (bnc#1198032).
• CVE-2018-20784: Fixed a denial of service (infinite loop in update_blocked_averages) by mishandled leaf cfs_rq in kernel/sched/fair.c (bnc#1126703).
• CVE-2018-7755: Fixed an issue in the fd_locked_ioctl function in drivers/block/floppy.c. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR (bnc#1084513).
• CVE-2020-10769: Fixed a buffer over-read flaw in the IPsec Cryptographic algorithm's module. This flaw allowed a local attacker with user privileges to cause a denial of service. (bnc#1173265)
• CVE-2021-28688: Fixed XSA-365 that includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values. This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died, leaving around zombie domains (bnc#1183646).

Seunghun Han discovered an information leak in the ACPI handling code in the Linux kernel when handling early termination of ACPI table loading. A local attacker could use this to expose sensitive informal (kernel address locations). (CVE-2017-13695)

It was discovered that a memory leak existed in the Serial Attached SCSI (SAS) implementation in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (memory exhaustion). (CVE-2018-10021)

It was discovered that the VirtIO subsystem in the Linux kernel did not properly initialize memory in some situations. A local attacker could use this to possibly expose sensitive information (kernel memory). (CVE-2018-1118)

Seunghun Han discovered an information leak in the ACPI handling code in the Linux kernel when handling early termination of ACPI table loading. A local attacker could use this to expose sensitive informal (kernel address locations). (CVE-2017-13695)

USN-3762-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 18.04 LTS for Ubuntu 16.04 LTS.
