LOWCVSS 3.7/10EPSS 0.45%

Last modified

CVE-2023-33855 is a low-severity vulnerability rated 3.7/10 on the CVSS scale. Under certain conditions, RSA operations performed by IBM Common Cryptographic Architecture (CCA) 7.0.0 through 7.5.36 may exhibit non-constant-time behavior. This could allow a remote attacker to obtain sensitive information using a timing-based attack. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
