CVE-2025-68792 (CNNVD-202601-2244)
中文标题:
Linux kernel 安全漏洞
英文标题:
tpm2-sessions: Fix out of range indexing in name_size
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于tpm2-sessions中name_size缺少范围检查，可能导致越界索引。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: tpm2-sessions: Fix out of range indexing in name_size 'name_size' does not have any range checks, and it just directly indexes with TPM_ALG_ID, which could lead into memory corruption at worst. Address the issue by only processing known values and returning -EINVAL for unrecognized values. Make also 'tpm_buf_append_name' and 'tpm_buf_fill_hmac_session' fallible so that errors are detected before causing any spurious TPM traffic. End also the authorization session on failure in both of the functions, as the session state would be then by definition corrupted.
