7.2
None Local Low Not required Complete Complete Complete
Linux drivers/char/lp.c Out-of-Bounds Write. Due to a missing bounds check, and the fact that parport_ptr integer is static, a 'secure boot' kernel command line adversary (can happen due to bootloader vulns, e.g. Google Nexus 6's CVE-2016-10277, where due to a vulnerability the adversary has partial control over the command line) can overflow the parport_nr array in the following code, by appending many (>LP_NO) 'lp=none' arguments to the command line.
702 CVE-2017-1000365 Bypass 2017-06-19 2019-10-02
7.2
Admin Local Low Not required Complete Complete Complete
The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but does not take the argument and environment pointers into account, which allows attackers to bypass this limitation. This affects Linux Kernel versions 4.11.5 and earlier. It appears that this feature was introduced in the Linux Kernel version 2.6.23.
703 CVE-2017-1000370 2017-06-19 2019-10-02
7.2
Admin Local Low Not required Complete Complete Complete
The offset2lib patch as used in the Linux Kernel contains a vulnerability that allows a PIE binary to be execve()'ed with 1GB of arguments or environmental strings then the stack occupies the address 0x80000000 and the PIE binary is mapped above 0x40000000 nullifying the protection of the offset2lib patch. This affects Linux Kernel version 4.11.5 and earlier. This is a different issue than CVE-2017-1000371. This issue appears to be limited to i386 based systems.
704 CVE-2017-1000371 2017-06-19 2019-10-02
7.2
None Local Low Not required Complete Complete Complete
The offset2lib patch as used by the Linux Kernel contains a vulnerability, if RLIMIT_STACK is set to RLIM_INFINITY and 1 Gigabyte of memory is allocated (the maximum under the 1/4 restriction) then the stack will be grown down to 0x80000000, and as the PIE binary is mapped above 0x80000000 the minimum distance between the end of the PIE binary's read-write segment and the start of the stack becomes small enough that the stack guard page can be jumped over by an attacker. This affects Linux Kernel version 4.11.5. This is a different issue than CVE-2017-1000370 and CVE-2017-1000365. This issue appears to be limited to i386 based systems.

** DISPUTED ** An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a "double fetch" vulnerability. NOTE: a third party reports that this is unexploitable because the doubly fetched value is not used.
734 CVE-2019-13272 264 2019-07-17 2019-07-25
7.2
None Local Low Not required Complete Complete Complete
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.

None Local Low Not required Complete Complete Complete
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
739 CVE-2019-15239 416 2019-08-20 2019-09-24
7.2
None Local Low Not required Complete Complete Complete
In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12, was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation. NOTE: this affects (for example) Linux distributions that use 4.9.x longterm kernels before 4.9.190 or 4.14.x longterm kernels before 4.14.139.
