CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to out-of-bounds read in RSA key exchange handling when processing an extremely short premaster secret from a client for a server using an RSA key backed by a PKCS#11 token. A remote attacker can send a specially crafted premaster secret to disclose sensitive information.

Only servers using an RSA key backed by a PKCS#11 token are vulnerable.
