CVE-2017-17863

CVE-2017-17863 affects the Linux kernel 4.9.x up to 4.9.71, where the BPF verifier in kernel/bpf/verifier.c fails to check the relationship between pointer values and the BPF stack. This can allow local users to trigger a denial of service (integer overflow or invalid memory access) or potentiall...

CVE-2017-17863

kernel/bpf/verifier.c in the Linux kernel 4.9.x through 4.9.71 does not check the relationship between pointer values and the BPF stack, which allows local users to cause a denial of service integer overflow or invalid memory access or possibly have unspecified other impact...

CVE-2017-17855

CVE-2017-17855 affects Linux kernel versions up to 4.14.8 in kernel/bpf/verifier.c, where improper use of pointers in place of scalars allows local users to cause a denial of service via memory corruption (impact described as high). The provided documents do not supply a confirmed exploit, mitiga...

CVE-2017-17852

CVE-2017-17852 affects the Linux kernel’s BPF verifier (kernel/bpf/verifier.c) up to version 4.14.8. The root cause is mishandling of 32-bit ALU operations, which can allow local users to cause a denial of service (memory corruption) and possibly other impact. The connected Nessus entries repeat ...

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...

CVE-2017-17853

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 incorrect BPFRSH signed bounds calculations...

CVE-2017-3196

PCAUSA Rawether framework does not properly validate BPF data, allowing a crafted malicious BPF program to perform operations on memory outside of its typical bounds on the driver's receipt of network packets. Local attackers can exploit this issue to execute arbitrary code with SYSTEM privileges...

CVE-2017-3196

CVE-2017-3196 concerns PCAUSA’s Rawether framework (Windows) failing to validate BPF data, enabling a crafted BPF program to read/write memory outside normal bounds when the NDIS receipt of packets occurs. This allows a local attacker to execute arbitrary code with SYSTEM privileges via a crafted...

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...
