Input validation

An out-of-bounds OOB memory access flaw was found in the Linux kernel's eBPF due to an Improper Input Validation. This flaw allows a local attacker with a special privilege to crash the system or leak internal information...

CVE-2021-4159

A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating som...

USN-5564-1 linux-intel-iotg vulnerabilities

Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not properly remove all references to a route filter before freeing it in some situations. A local attacker could use this to cause a denial of service system crash or execute arbitrary code...

Peetch - An eBPF Playground

peetch is a collection of tools aimed at experimenting with different aspects of eBPF to bypass TLS protocol protections. Currently, peetch includes two subcommands. The first called dump aims to sniff network traffic by associating information about the source process with each packet. The secon...
