[PATCH bpf 0/2] bpf: Fix and test cgroup storage OOB issue

Posted by xulang 2 weeks, 6 days ago

This series fixes an out-of-bounds read in BPF cgroup storage when the
value_size is not 8-byte aligned. The fix ensures proper alignment during
buffer allocation, and a test case is added to prevent regression.
