CVE-2026-72402
Description
AI Translation Available
In the Linux kernel, the following vulnerability has been resolved:
bpf: Mask pseudo pointer values in verifier logs
print_bpf_insn() masks ldimm64 immediates for pointer-bearing pseudo
sources when pointer leaks are not allowed, but the mask only covers
BPF_PSEUDO_MAP_FD and BPF_PSEUDO_MAP_VALUE.
BPF_PSEUDO_MAP_IDX, BPF_PSEUDO_MAP_IDX_VALUE, and BPF_PSEUDO_BTF_ID can
also be resolved to kernel pointer values before the verifier log prints
the instruction. Include them in the existing pointer classification so
the log prints 0x0 instead of the rewritten address.
