Title
Apache Commons BCEL: Nested Code/Record attributes drive unbounded parse-time recursion in ClassParser
Summary
Symbolic name not mapping to correct object vulnerability in Apache Commons.
BCEL caches attacker-controlled classes under their self-declared names without validating the requested name, allowing subsequent lookups and name-keyed verification results to refer to a different class.
This issue affects Apache Commons: before 6.13.0.
Users are recommended to upgrade to version 6.13.0, which fixes the issue.

GHSA-PHJ2-V9XX-8M7R
Vulnerability from github – Published: 2026-06-24 18:32 – Updated: 2026-06-30 03:37
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
bpf: Enforce regsafe base id consistency for BPF_ADD_CONST scalars
When regsafe() compares two scalar registers that both carry BPF_ADD_CONST, check_scalar_ids() maps their full compound id (aka base | BPF_ADD_CONST flag) as one idmap entry. However, it never verifies that the underlying base ids, that is, with the flag stripped are consistent with existing idmap mappings.
This allows construction of two verifier states where the old state has R3 = R2 + 10 (both sharing base id A) while the current state has R3 = R4 + 10 (base id C, unrelated to R2). The idmap creates two independent entries: A->B (for R2) and A|flag->C|flag (for R3), without catching that A->C conflicts with A->B. State pruning then incorrectly succeeds.
Fix this by additionally verifying base ID mapping consistency whenever BPF_ADD_CONST is set: after mapping the compound ids, also invoke check_ids() on the base IDs (flag bits stripped). This ensures that if A was already mapped to B from comparing the source register, any ADD_CONST derivative must also derive from B, not an unrelated C.
