Linux Kernel Denial of Service Vulnerability (CNVD-2018-10153)
The Linux kernel is a computer operating system kernel written in C and assembly language, compliant with the POSIX standard, and distributed under the GNU General Public License. Linux Kernel suffers from a ptrace error handling denial of service vulnerability. A local user can exploit this...
UBUNTU-CVE-2018-1000199
The Linux Kernel version 3.18 contains a dangerous feature vulnerability in modifyuserhwbreakpoint that can result in crash and possibly memory corruption. This attack appear to be exploitable via local code execution and the ability to use ptrace. This vulnerability appears to have been fixed in...

kernel: exec/ptrace: get_dumpable() incorrect tests
A flaw was found in the way the getdumpable function return value was interpreted in the ptrace subsystem of the Linux kernel. When 'fs.suiddumpable' was set to 2, a local, unprivileged local user could use this flaw to bypass intended ptrace restrictions and obtain potentially sensitive...
Linux kernel denial of service vulnerability (CNVD-2018-07889)
The Linux kernel is a computer operating system kernel written in C and assembly language, compliant with the POSIX standard, and distributed under the GNU General Public License. A denial of service vulnerability exists in the flushtmregstothread function in arch/powerpc/kernel/ptrace.c in Linux...
DEBIAN-CVE-2018-1091
In the flushtmregstothread function in arch/powerpc/kernel/ptrace.c in the Linux kernel before 4.13.5, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory TM...

FreeBSD : FreeBSD -- Kernel data leak via ptrace(PT_LWPINFO) (34a3f9b5-dab3-11e7-b5af-a4badb2f4699)
Not all information in the struct ptracelwpinfo is relevant for the state of any thread, and the kernel does not fill the irrelevant bytes or short strings. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information of the kernel stack...
FreeBSD 10.3 / 10.4 / 11.0 / 11.1 : ptrace / kldstat Information Disclosure Vulnerabilities (FreeBSD-SA-17:08.ptrace) (FreeBSD-SA-17:10.kldstat)
The version of the FreeBSD kernel running on the remote host is prior to 10.3-RELEASE-p24, 10.4 prior to 10.4-RELEASE-p3, 11.0 prior to 11.0-RELEASE-p15, or 11.1 prior to 11.1-RELEASE-p4. It is, therefore, affected by a potential information disclosure vulnerabilities in ptrace and kldstat. An...
FreeBSD Information Disclosure Vulnerability (CNVD-2017-37249)
FreeBSD is a type of UNIX operating system, an important branch of Unix that evolved from BSD, 386BSD and 4.4BSD. FreeBSD suffers from an information disclosure vulnerability. The vulnerability arises because the ptrace2 system call fails to properly initialize the ptracelwpinfo structure. A loca...
