CVE-2026-53076 is a high-severity vulnerability in the Linux kernel's BPF subsystem involving an out-of-bounds (OOB) read. The flaw occurs when copying data from a BPF_MAP_TYPE_CGROUP_STORAGE map to a per-CPU (pcpu) map when the value size is not aligned to 8 bytes. This mismatch leads to an OOB read due to incorrect assumptions about data size rounding.
