Here are two patches for ecdsa to avoid reporting nonsensical values for enc/dec size and -- for P521 keys -- also the key size in response to KEYCTL_PKEY_QUERY system calls. Resending as requested by Herbert: https://lore.kernel.org/r/Z9fuCTAAOphOvEeH@xxxxxxxxxxxxxxxxxxx/ Link to the original submission: https://lore.kernel.org/r/cover.1738521533.git.lukas@xxxxxxxxx/ Although these are technically fixes, the issues they address are not critical, so I recommend not applying as fixes for v6.15, but rather let the patches soak in linux-next for v6.16.
