CVE-2021-3490 Linux kernel eBPF bitwise ops ALU32 bounds tracking
The eBPF ALU32 bounds tracking for bitwise ops AND, OR and XOR in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e "bpf: Fix...

CVE-2021-3490
A flaw was found in the Linux kernels eBPF verification code. It was discovered that eBPF ALU32 bounds tracking for bitwise ops AND, OR and XOR did not update the 32-bit bounds. By default accessing the eBPF verifier is only accessible to privileged users with CAPSYSADMIN. A local user with the...

Linux kernel 缓冲区错误漏洞
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel. The vulnerability stems from the discovery that the eBPF ALU32 bounds trace for bitwise operations AND, OR and XOR does not...

CVE-2020-27194
CVE-2020-27194 affects the Linux kernel prior to 5.8.15. The issue is in the eBPF verifier: scalar32_min_max_or() incorrectly copies a 64‑bit value into a 32‑bit variable, causing integer truncation and incorrect bounds tracking. This misalignment between verifier time checks and actual execution...
