A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure (kernel memory), and possibly out-of-bounds writes that could potentially lead to code execution. This issue was addressed in the upstream kernel in commit 9b00f1b78809 (&#34;bpf: Fix truncation handling for mod32 dst reg wrt zero&#34;) and in Linux stable kernels 5.11.2, 5.10.19, and 5.4.101.</p> <p><strong>Affected:</strong> Linux kernel</p> <p>The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0.
