SPDX-License-Identifier: GPL-2.0 + +SRBDS - Special Register Buffer Data Sampling +============================================= + +SRBDS is a hardware vulnerability that allows MDS :doc:`mds` techniques to +infer values returned from special register accesses. Special register +accesses are accesses to off core registers. According to Intel's evaluation, +the special register reads that have a security expectation of privacy are +RDRAND, RDSEED and SGX EGETKEY. + +When RDRAND, RDSEED and EGETKEY instructions are used, the data is moved +to the core through the special register mechanism that is susceptible +to MDS attacks. + +Affected processors +-------------------- +Core models (desktop, mobile, Xeon-E3) that implement RDRAND and/or RDSEED may +be affected. + +A processor is affected by SRBDS if its Family_Model and stepping is +in the following list, with the exception of the listed processors +exporting MDS_NO while Intel TSX is available yet not enabled. The +latter class of processors are only affected when Intel TSX is enabled +by software using TSX_CTRL_MSR otherwise they are not affected. + + ============= ============ ======== + common name Family_Model Stepping + ============= ============ ======== + IvyBridge 06_3AH All + + Haswell 06_3CH All + Haswell_L 06_45H All + Haswell_G 06_46H All + + Broadwell_G 06_47H All + Broadwell 06_3DH All + + Skylake_L 06_4EH All + Skylake 06_5EH All + + Kabylake_L 06_8EH <= 0xC + Kabylake 06_9EH <= 0xD + ============= ============ ======== + +Related CVEs +------------ + +The following CVE entry is related to this SRBDS issue: + + ============== ===== ===================================== + CVE-2020-0543 SRBDS Special Register Buffer Data Sampling + ============== ===== ===================================== + +Attack scenarios +---------------- +An unprivileged user can extract values returned from RDRAND and RDSEED +executed on another core or sibling thread using MDS techniques. + + +Mitigation mechanism +------------------- +Intel will release microcode updates that modify the RDRAND, RDSEED, and +EGETKEY instructions to overwrite secret special register data in the shared +staging buffer before the secret data can be accessed by another logical +processor. + +During execution of the RDRAND, RDSEED, or EGETKEY instructions, off-core +accesses from other logical processors will be delayed until the special +register read is complete and the secret data in the shared staging buffer is +overwritten. + +This has three effects on performance: + +#. RDRAND, RDSEED, or EGETKEY instructions have higher latency. + +#. Executing RDRAND at the same time on multiple logical processors will be + serialized, resulting in an overall reduction in the maximum RDRAND + bandwidth. + +#. Executing RDRAND, RDSEED or EGETKEY will delay memory accesses from other + logical processors that miss their core caches, with an impact similar to + legacy locked cache-line-split accesses. + +The microcode updates provide an opt-out mechanism (RNGDS_MITG_DIS) to disable +the mitigation for RDRAND and RDSEED instructions executed outside of Intel +Software Guard Extensions (Intel SGX) enclaves. On logical processors that +disable the mitigation using this opt-out mechanism, RDRAND and RDSEED do not +take longer to execute and do not impact performance of sibling logical +processors memory accesses. The opt-out mechanism does not affect Intel SGX +enclaves (including execution of RDRAND or RDSEED inside an enclave, as well +as EGETKEY execution). + +IA32_MCU_OPT_CTRL MSR Definition +-------------------------------- +Along with the mitigation for this issue, Intel added a new thread-scope +IA32_MCU_OPT_CTRL MSR, (address 0x123). The presence of this MSR and +RNGDS_MITG_DIS (bit 0) is enumerated by CPUID.(EAX=07H,ECX=0).EDX[SRBDS_CTRL = +9]==1. This MSR is introduced through the microcode update. + +Setting IA32_MCU_OPT_CTRL[0] (RNGDS_MITG_DIS) to 1 for a logical processor +disables the mitigation for RDRAND and RDSEED executed outside of an Intel SGX +enclave on that logical processor. Opting out of the mitigation for a +particular logical processor does not affect the RDRAND and RDSEED mitigations +for other logical processors. + +Note that inside of an Intel SGX enclave, the mitigation is applied regardless +of the value of RNGDS_MITG_DS. + +Mitigation control on the kernel command line +--------------------------------------------- +The kernel command line allows control over the SRBDS mitigation at boot time +with the option "srbds=". The option for this is: + + ============= ============================================================= + off This option disables SRBDS mitigation for RDRAND and RDSEED on + affected platforms. + ============= ============================================================= + +SRBDS System Information +----------------------- +The Linux kernel provides vulnerability status information through sysfs.
