CVE-2026-89609

CVE-2026-89609 is a race condition in the eCryptfs component of the Linux kernel. The function ecryptfs_exorcise_daemon() drops queued messages from a dying daemon without holding the ecryptfs_msg_ctx_lists_mux lock, which ecryptfs_msg_ctx_alloc_to_free() requires. This allows concurrent access t...

CVE-2026-89608

CVE-2026-89608 affects the ecryptfs component of the Linux kernel. The function ecryptfs_parse_packet_set() calculates the remaining packet buffer size from PAGE_SIZE - 8 instead of the actual packet set buffer length, which can overstate the available buffer for version 1 headers . According to ...

CVE-2026-89607

CVE-2026-89607 affects the Linux kernel's ecryptfs module. The function parse_tag_3_packet() fails to bound encrypted_key_size against ECRYPTFS_MAX_KEY_BYTES (64) in the passphrase decryption path. When the value exceeds 64, two out-of-bounds writes corrupt the ecryptfs_auth_tok and ecryptfs_cryp...
