The vulnerability in the kernel/bpf/verifier.c component of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability in the kernel/bpf/verifier.c component of the Linux operating system is related to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the...

Vulnerability of the `scalar32_min_max_or` function in the Linux operating system’s kernel/bpf/verifier.c file, which allows a hacker to trigger a service failure

The vulnerability of the scalar32minmaxor function in the Linux kernel’s bpf/verifier.c file is related to operations that go beyond the buffer boundaries in memory. Exploiting this vulnerability could allow an attacker to trigger a system failure...

USN-4626-1: Linux kernel vulnerabilities

Simon Scannell discovered that the bpf verifier in the Linux kernel did not properly calculate register bounds for certain operations. A local attacker could use this to expose sensitive information kernel memory or gain administrative privileges. CVE-2020-27194 Moritz Lipp, Michael Schwarz,...

An issue was discovered in the Linux kernel before 5.8.15. scalar32_min_max_or in kernel/bpf/verifier.c mishandles bounds tracking during use of 64-bit values aka CID-5b9fbeb75b6a.

Internet Bug Bounty: [CVE-2020-27194] Linux kernel: eBPF verifier bug in `or` binary operation tracking function leads to LPE

CVE-2020-27194 is a eBPF verifier bug that allows an unprivileged attacker to create BPF socket filter programs that can read and write Out of Bounds, trough which an arbitrary kernel read write can be achieved. I'm taking the root cause explanation from the patch email: Simon reported an issue...

CVE-2020-15214

In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger a write out bounds / segmentation fault if the segment ids are not sorted. Code assumes that the segment ids are in increasing order, using the last element of the tensor holding them to determine the...

CVE-2020-15211

In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indice...
