hw: cpu: speculative store bypass

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.

NVIDIA Jetson Linux contains a vulnerability in UEFI, where improper authentication may allow a privileged user to cause corruption of the Linux Device Tree. A successful exploitation of this vulnerability might lead to data tampering, denial of service.

NVIDIA Jetson Linux and IGX OS contain a vulnerability in NvMap, where improper tracking of memory allocations could allow a local attacker to cause memory overallocation. A successful exploitation of this vulnerability might lead to denial of service.

NVIDIA Trusted OS contains a vulnerability in an SMC call handler, where failure to validate untrusted input may allow a highly privileged local attacker to cause information disclosure and compromise integrity. The scope of the impact can extend to other components.

NVIDIA Jetson Linux Driver Package contains a vulnerability in nvbootctrl, where a privileged local attacker can configure invalid settings, resulting in denial of service.

NVIDIA Jetson Linux Driver Package contains a vulnerability in the Cboot blob_decompress function, where insufficient validation of untrusted data may allow a local attacker with elevated privileges to cause a memory buffer overflow, which may lead to code execution, limited loss of Integrity, and limited denial of service. The scope of impact can extend to other components.

NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller which may allow a user with elevated privileges to gain access to information from unscrubbed memory, which may lead to information disclosure.

NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller which may allow a user with elevated privileges to gain access to information from unscrubbed registers, which may lead to information disclosure.

Bootloader contains a vulnerability in NVIDIA MB2, which may cause free-the-wrong-heap, which may lead to limited denial of service.

Bootloader contains a vulnerability in access permission settings where unauthorized software may be able to overwrite NVIDIA MB2 code, which would result in limited denial of service.

Trusty contains a vulnerability in the NVIDIA OTE protocol that is present in all TAs. An incorrect message stream deserialization allows an attacker to use the malicious CA that is run by the user to cause the buffer overflow, which may lead to information disclosure and data modification.

Trusty contains a vulnerability in TSEC TA which deserializes the incoming messages even though the TSEC TA does not expose any command. This vulnerability might allow an attacker to exploit the deserializer to impact code execution, causing information disclosure.

Trusty contains a vulnerability in NVIDIA OTE protocol message parsing code, which is present in all the TAs. An incorrect bounds check can allow a local user through a malicious client to access memory from the heap in the TrustZone, which may lead to information disclosure.

Bootloader contains a vulnerability in NVIDIA TegraBoot where a potential heap overflow might allow an attacker to control all the RAM after the heap block, leading to denial of service or code execution.

Bootloader contains a vulnerability in NVIDIA MB2 where a potential heap overflow could cause memory corruption, which might lead to denial of service or code execution.

Bootloader contains a vulnerability in NVIDIA MB2 where a potential heap overflow might lead to denial of service or escalation of privileges.

Bootloader contains a vulnerability in NVIDIA MB2 where potential heap overflow might cause corruption of the heap metadata, which might lead to arbitrary code execution, denial of service, and information disclosure during secure boot.

Trusty contains a vulnerability in the HDCP service TA where bounds checking in command 10 is missing. The length of an I/O buffer parameter is not checked, which might lead to memory corruption.

Trusty contains a vulnerability in the HDCP service TA where bounds checking in command 11 is missing. Improper restriction of operations within the bounds of a memory buffer might lead to information disclosure, denial of service, or escalation of privileges.

Trusty contains a vulnerability in the HDCP service TA where bounds checking in command 9 is missing. Improper restriction of operations within the bounds of a memory buffer might lead to escalation of privileges, information disclosure, and denial of service.
