Summary
A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key.
Exploit prediction (EPSS)
0.32% probability of exploitation in the next 30 days, higher than 25% of all scored CVEs.
