CVE-2023-42811 is a medium-severity vulnerability affecting the aes-gcm Rust crate versions 0.10.0 through 0.10.2, and products utilizing these versions such as Fedora. The vulnerability allows the decrypted plaintext to be exposed even if GCM tag verification fails, potentially enabling Chosen Ciphertext Attacks (CCAs) and full plaintext recovery if the program accesses the buffer after decryption failure. With a CVSS score of 5.5 (Medium), it requires local access and low privileges, but can lead to high confidentiality impact. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
