CVE-2026-72426 bpf: Preserve pointer spill metadata during half-slot cleanup

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve pointer spill metadata during half-slot cleanup cleanfuncstate cleans dead stack slots in 4-byte halves. When the high half of a STACKSPILL slot is dead and the low half remains live, cleanup converts the live low...

CVE-2026-72423

The CVE-2026-72423 vulnerability affects the Linux kernel’s BPF conntrack error reporting: wrappers for conntrack kfuncs may write to opts->error outside the verifier-checked range, for certain sizes. The issue occurs when using an opts pointer with an accompanying opts__sz argument; the verif...

CVE-2026-72402 bpf: Mask pseudo pointer values in verifier logs

In the Linux kernel, the following vulnerability has been resolved: bpf: Mask pseudo pointer values in verifier logs printbpfinsn masks ldimm64 immediates for pointer-bearing pseudo sources when pointer leaks are not allowed, but the mask only covers BPFPSEUDOMAPFD and BPFPSEUDOMAPVALUE...

CVE-2026-72402

CVE-2026-72402 : In the Linux kernel, the bpf verifier logs could reveal kernel pointer values via ldimm64 immediates for pointer-bearing pseudo sources. The function print_bpf_insn() previously masked only BPF_PSEUDO_MAP_FD and BPF_PSEUDO_MAP_VALUE; the risk extended to BPF_PSEUDO_MAP_IDX, BPF_P...

CVE-2026-72401

CVE-2026-72401 affects the Linux kernel’s BPF verifier path. The root cause is a leak of env->insn_aux_data when allocation of env->succ fails after env->insn_aux_data is allocated, due to vfree being placed before the err_free_env path. The fix moves vfree(env->insn_aux_data) into er...
