Frank Buss discovered that OpenSSL had a heap buffer over-read in ASN.1 content parsing. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or obtain sensitive information. (CVE-2026-34180)
Pavol Zacik and Alex Gaynor discovered that OpenSSL incorrectly accepted PKCS#12 files with short HMAC keys when using PBMAC1. An attacker could possibly use this issue to bypass integrity checks. This issue only affected Ubuntu 25.10 and Ubuntu 26.04 LTS. (CVE-2026-34181)
Asim Viladi Oglu Manizada and Alex Gaynor discovered that OpenSSL could accept forged CMS AuthEnvelopedData messages. An attacker could possibly use this issue to bypass message authentication checks. (CVE-2026-34182)
Abhinav Agarwal discovered that OpenSSL had unbounded memory growth in the QUIC PATH_CHALLENGE handler. A remote attacker could possibly use this issue to cause OpenSSL to use excessive resources, leading to a denial of service. This issue only affected Ubuntu 25.10 and Ubuntu 26.04 LTS. (CVE-2026-34183)
Sunwoo Lee, Hyuk Lim, and Seunghyun Yoon discovered that OpenSSL had a NULL pointer dereference in QUIC server initial packet handling. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 25.10 and Ubuntu 26.04 LTS. (CVE-2026-42764)
Mayank Jangid, Kushal Khemka, Hari Priandana, Bhabani Sankar Das, and Qifan Zhang discovered that OpenSSL had a possible NULL dereference in password- based CMS decryption. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2026-42766)
Zhanpeng Liu, Guannan Wang, and Guancheng Li discovered that OpenSSL had a NULL pointer dereference in CRMF EncryptedValue decryption. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2026-42767)
Alex Gaynor discovered that OpenSSL had a Bleichenbacher oracle in CMS_decrypt() and PKCS7_decrypt() with multiple RecipientInfo values. An attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 25.10 and Ubuntu 26.04 LTS. (CVE-2026-42768)
Alex Gaynor discovered that OpenSSL had a trust-anchor substitution issue in CMP rootCaKeyUpdate processing. An attacker could possibly use this issue to bypass certificate trust validation. This issue only affected Ubuntu 25.10 and Ubuntu 26.04 LTS. (CVE-2026-42769)
Alex Gaynor discovered that OpenSSL used attacker-supplied parameters when validating FFC-DH peers. An attacker could possibly use this issue to weaken key validation and compromise security guarantees. (CVE-2026-42770)
Alex Gaynor discovered that OpenSSL could ignore the IV in AES-OCB mode on the EVP_Cipher() path. An attacker could possibly use this issue to bypass cryptographic protections and obtain sensitive information. (CVE-2026-45445)
Alex Gaynor discovered that OpenSSL had incorrect tag processing for empty messages in AES-GCM-SIV and AES-SIV modes. An attacker could possibly use this issue to bypass cryptographic integrity checks. (CVE-2026-45446)
Thai Duong discovered that OpenSSL had a heap use-after-free in PKCS7_verify(). An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-45447)
Zehua Qiao and Jinwen He discovered that OpenSSL had a possible heap buffer overflow in ASN.1 multibyte string conversion. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-7383)
Bhabani Sankar Das discovered that OpenSSL had an out-of-bounds read in CMS password-based decryption. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2026-9076)
