About this tag
The asymmetric keys tag on WindowsForum.com covers discussions about cryptographic key pairs used in public-key infrastructure, with a focus on security vulnerabilities and patches. Recent content includes a thread about CVE-2025-68724, a Linux kernel bug in the asymmetric_keys subsystem that could lead to buffer overflows from untrusted X.509 fields. The fix involves explicit overflow checks in asymmetric_key_generate_id. While the tag is primarily associated with Linux kernel security, it may also relate to broader topics like encryption, digital signatures, and certificate handling. Users can find technical details on kernel patches, integer overflow prevention, and secure allocation practices for asymmetric key operations.

    CVE-2025-68724 Linux Kernel: Safe Allocation in Asymmetric Keys

    The Linux kernel team has assigned CVE-2025-68724 to a recently patched integer‑overflow bug in the asymmetric_keys subsystem — a defensive fix that uses explicit overflow checks (check_add_overflow/size_add/struct_size) in asymmetric_key_generate_id to prevent a potential buffer overflow when...
