Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from insufficient error checking in the ahashhmacinit function in the crypto:bcm module...

The vulnerability of the tpm_buf_check_hmac_response() function in the Linux operating system’s TPM kernel allows a hacker to induce a service failure.

The vulnerability of the tpmbufcheckhmacresponse function in the drivers/char/tpm/tpm2-sessions.c file of the Trusted Platform Module TPM driver for the Linux operating system is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to trigger a servic...
