Linux kernel information disclosure vulnerability (CNVD-2017-38519)

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. An information disclosure vulnerability exists in Linux kernel versions 4.14.8 and earlier. The vulnerability arises...

CVE-2017-17857

The checkstackboundary function in kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging mishandling of invalid variable stack read operations...

Linux BPF Sign Extension Local Privilege Escalation

Linux kernel prior to 4.14.8 contains a vulnerability in the Berkeley Packet Filter BPF verifier. The checkaluop function performs incorrect sign extension which allows the verifier to be bypassed, leading to arbitrary kernel read/write. The target system must be compiled with BPF support and...

DEBIAN-CVE-2017-9150

The docheck function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allowptrleaks value available for restricting the output of the printbpfinsn function, which allows local users to obtain sensitive address information via crafted bpf system calls...

CVE-2017-9150

The docheck function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allowptrleaks value available for restricting the output of the printbpfinsn function, which allows local users to obtain sensitive address information via crafted bpf system calls...

UBUNTU-CVE-2017-9150

The docheck function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allowptrleaks value available for restricting the output of the printbpfinsn function, which allows local users to obtain sensitive address information via crafted bpf system calls...

UBUNTU-CVE-2016-4557

The replacemapfdwithmapptr function in kernel/bpf/verifier.c in the Linux kernel before 4.5.5 does not properly maintain an fd data structure, which allows local users to gain privileges or cause a denial of service use-after-free via crafted BPF instructions that reference an incorrect file...

CVE-2016-2383

The adjustbranches function in kernel/bpf/verifier.c in the Linux kernel before 4.5 does not consider the delta in the backward-jump case, which allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions...
