1 CVE-2018-20511 200 +Info 2018-12-27 2019-04-01
2.1
None Local Low Not required Partial None None
An issue was discovered in the Linux kernel before 4.18.11. The ipddp_ioctl function in drivers/net/appletalk/ipddp.c allows local users to obtain sensitive kernel address information by leveraging CAP_NET_ADMIN to read the ipddp_route dev and next fields via an SIOCFINDIPDDPRT ioctl call.
2 CVE-2018-19854 200 +Info 2018-12-04 2019-11-06
1.9
None Local Medium Not required Partial None None
An issue was discovered in the Linux kernel before 4.19.3. crypto_report_one() and related functions in crypto/crypto_user.c (the crypto user configuration API) do not fully initialize structures that are copied to userspace, potentially leaking sensitive memory to user programs. NOTE: this is a CVE-2013-2547 regression but with easier exploitability because the attacker does not need a capability (however, the system must have the CONFIG_CRYPTO_USER kconfig option).
3 CVE-2018-18710 200 +Info 2018-10-29 2019-04-03
2.1
None Local Low Not required Partial None None
An issue was discovered in the Linux kernel through 4.19. 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.
4 CVE-2018-16862 200 +Info 2018-11-26 2019-04-01
2.1
None Local Low Not required Partial None None
A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one.
5 CVE-2018-16658 200 +Info 2018-09-07 2019-08-06
3.6
None Local Low Not required Partial None Partial
An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status 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.
6 CVE-2018-15594 200 +Info 2018-08-20 2019-10-03
2.1
None Local Low Not required Partial None None
arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests.
7 CVE-2018-15471 125 DoS Overflow +Info 2018-08-17 2020-08-24
6.8
None Local Low ??? Complete Complete Complete
An issue was discovered in xenvif_set_hash_mapping in drivers/net/xen-netback/hash.c in the Linux kernel through 4.18.1, as used in Xen through 4.11.x and other products. The Linux netback driver allows frontends to control mapping of requests to request queues. When processing a request to set or change this mapping, some input validation (e.g., for an integer overflow) was missing or flawed, leading to OOB access in hash handling. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in one or more of privilege escalation, Denial of Service (DoS), or information leaks.
8 CVE-2018-12633 362 DoS +Info 2018-06-22 2018-08-21
6.3
None Local Medium Not required Complete None Complete
An issue was discovered in the Linux kernel through 4.17.2. vbg_misc_device_ioctl() in drivers/virt/vboxguest/vboxguest_linux.c reads the same user data twice with copy_from_user. The header part of the user data is double-fetched, and a malicious user thread can tamper with the critical variables (hdr.size_in and hdr.size_out) in the header between the two fetches because of a race condition, leading to severe kernel errors, such as buffer over-accesses. This bug can cause a local denial of service and information leakage.
9 CVE-2018-11508 200 +Info 2018-05-28 2019-03-27
2.1
None Local Low Not required Partial None None
The compat_get_timex function in kernel/compat.c in the Linux kernel before 4.16.9 allows local users to obtain sensitive information from kernel memory via adjtimex.
10 CVE-2018-7755 200 Bypass +Info 2018-03-08 2018-10-04
2.1
None Local Low Not required Partial None None
An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. 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.
11 CVE-2018-7754 532 +Info 2018-08-10 2020-08-24
2.1
None Local Low Not required Partial None None
The aoedisk_debugfs_show function in drivers/block/aoe/aoeblk.c in the Linux kernel through 4.16.4rc4 allows local users to obtain sensitive address information by reading "ffree: " lines in a debugfs file.
12 CVE-2018-7273 200 Bypass +Info 2018-02-21 2019-03-01
4.9
None Local Low Not required Complete None None
In the Linux kernel through 4.15.4, the floppy driver reveals the addresses of kernel functions and global variables using printk calls within the function show_floppy in drivers/block/floppy.c. An attacker can read this information from dmesg and use the addresses to find the locations of kernel code and data and bypass kernel security protections such as KASLR.
13 CVE-2018-6412 200 +Info 2018-01-31 2019-03-20
5.0
None Remote Low Not required Partial None None
In the function sbusfb_ioctl_helper() in drivers/video/fbdev/sbuslib.c in the Linux kernel through 4.15, an integer signedness error allows arbitrary information leakage for the FBIOPUTCMAP_SPARC and FBIOGETCMAP_SPARC commands.
14 CVE-2018-5995 200 +Info 2018-08-07 2019-05-28
2.1
None Local Low Not required Partial None None
The pcpu_embed_first_chunk function in mm/percpu.c in the Linux kernel through 4.14.14 allows local users to obtain sensitive address information by reading dmesg data from a "pages/cpu" printk call.
15 CVE-2018-5953 200 +Info 2018-08-07 2021-01-28
2.1
None Local Low Not required Partial None None
The swiotlb_print_info function in lib/swiotlb.c in the Linux kernel through 4.14.14 allows local users to obtain sensitive address information by reading dmesg data from a "software IO TLB" printk call.
16 CVE-2018-5750 200 +Info 2018-01-26 2019-03-07
2.1
None Local Low Not required Partial None None
The acpi_smbus_hc_add function in drivers/acpi/sbshc.c in the Linux kernel through 4.14.15 allows local users to obtain sensitive address information by reading dmesg data from an SBS HC printk call.
17 CVE-2018-1118 200 +Info 2018-05-10 2019-10-09
2.1
None Local Low Not required Partial None None
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
18 CVE-2017-16911 200 +Info 2018-01-31 2018-08-24
1.9
None Local Medium Not required Partial None None
The vhci_hcd driver in the Linux Kernel before version 4.14.8 and 4.4.114 allows allows local attackers to disclose kernel memory addresses. Successful exploitation requires that a USB device is attached over IP.
19 CVE-2017-7558 125 +Info 2018-07-26 2019-10-09
5.0
None Remote Low Not required Partial None None
A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace.
