It's meant to be as concise as possible, focused only on +the current kernel mitigations: what are the RSB-related attack vectors +and how are they currently being mitigated? + +It's *not* meant to describe how the RSB mechanism operates or how the +exploits work. More details about those can be found in the references +below. + +Rather, this is basically a glorified comment, but too long to actually +be one. So when the next CVE comes along, a kernel developer can +quickly refer to this as a refresher to see what we're actually doing +and why. + +At a high level, there are two classes of RSB attacks: RSB poisoning +(Intel and AMD) and RSB underflow (Intel only). They must each be +considered individually for each attack vector (and microarchitecture +where applicable). + +---- + +RSB poisoning (Intel and AMD) +============================= + +SpectreRSB +~~~~~~~~~~ + +RSB poisoning is a technique used by SpectreRSB [#spectre-rsb]_ where +an attacker poisons an RSB entry to cause a victim's return instruction +to speculate to an attacker-controlled address. This can happen when +there are unbalanced CALLs/RETs after a context switch or VMEXIT. + +* All attack vectors can potentially be mitigated by flushing out any + poisoned RSB entries using an RSB filling sequence + [#intel-rsb-filling]_ [#amd-rsb-filling]_ when transitioning between + untrusted and trusted domains. But this has a performance impact and + should be avoided whenever possible. + + .. DANGER:: + **FIXME**: Currently we're flushing 32 entries. However, some CPU + models have more than 32 entries. The loop count needs to be + increased for those. More detailed information is needed about RSB + sizes. + +* On context switch, the user->user mitigation requires ensuring the + RSB gets filled or cleared whenever IBPB gets written [#cond-ibpb]_ + during a context switch: + + * AMD: + On Zen 4+, IBPB (or SBPB [#amd-sbpb]_ if used) clears the RSB. + This is indicated by IBPB_RET in CPUID [#amd-ibpb-rsb]_. + + On Zen < 4, the RSB filling sequence [#amd-rsb-filling]_ must be + always be done in addition to IBPB [#amd-ibpb-no-rsb]_. This is + indicated by X86_BUG_IBPB_NO_RET. + + * Intel: + IBPB always clears the RSB: + + "Software that executed before the IBPB command cannot control + the predicted targets of indirect branches executed after the + command on the same logical processor. The term indirect branch + in this context includes near return instructions, so these + predicted targets may come from the RSB." [#intel-ibpb-rsb]_ + +* On context switch, user->kernel attacks are prevented by SMEP. User + space can only insert user space addresses into the RSB. Even + non-canonical addresses can't be inserted due to the page gap at the + end of the user canonical address space reserved by TASK_SIZE_MAX. + A SMEP #PF at instruction fetch prevents the kernel from speculatively + executing user space. + + * AMD: + "Finally, branches that are predicted as 'ret' instructions get + their predicted targets from the Return Address Predictor (RAP). + AMD recommends software use a RAP stuffing sequence (mitigation + V2-3 in [2]) and/or Supervisor Mode Execution Protection (SMEP) + to ensure that the addresses in the RAP are safe for + speculation. Collectively, we refer to these mitigations as "RAP + Protection"." [#amd-smep-rsb]_ + + * Intel: + "On processors with enhanced IBRS, an RSB overwrite sequence may + not suffice to prevent the predicted target of a near return + from using an RSB entry created in a less privileged predictor + mode. Software can prevent this by enabling SMEP (for + transitions from user mode to supervisor mode) and by having + IA32_SPEC_CTRL.IBRS set during VM exits." [#intel-smep-rsb]_ + +* On VMEXIT, guest->host attacks are mitigated by eIBRS (and PBRSB + mitigation if needed): + + * AMD: + "When Automatic IBRS is enabled, the internal return address + stack used for return address predictions is cleared on VMEXIT." + [#amd-eibrs-vmexit]_ + + * Intel: + "On processors with enhanced IBRS, an RSB overwrite sequence may + not suffice to prevent the predicted target of a near return + from using an RSB entry created in a less privileged predictor + mode. Software can prevent this by enabling SMEP (for + transitions from user mode to supervisor mode) and by having + IA32_SPEC_CTRL.IBRS set during VM exits. Processors with + enhanced IBRS still support the usage model where IBRS is set + only in the OS/VMM for OSes that enable SMEP. To do this, such + processors will ensure that guest behavior cannot control the + RSB after a VM exit once IBRS is set, even if IBRS was not set + at the time of the VM exit." [#intel-eibrs-vmexit]_ + + Note that some Intel CPUs are susceptible to Post-barrier Return + Stack Buffer Predictions (PBRSB) [#intel-pbrsb]_, where the last + CALL from the guest can be used to predict the first unbalanced RET. + In this case the PBRSB mitigation is needed in addition to eIBRS. + +AMD RETBleed / SRSO / Branch Type Confusion +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +On AMD, poisoned RSB entries can also be created by the AMD RETBleed +variant [#retbleed-paper]_ [#amd-btc]_ or by Speculative Return Stack +Overflow [#amd-srso]_ (Inception [#inception-paper]_). The kernel +protects itself by replacing every RET in the kernel with a branch to a +single safe RET. + +---- + +RSB underflow (Intel only) +========================== + +RSB Alternate (RSBA) ("Intel Retbleed") +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Some Intel Skylake-generation CPUs are susceptible to the Intel variant +of RETBleed [#retbleed-paper]_ (Return Stack Buffer Underflow +[#intel-rsbu]_). If a RET is executed when the RSB buffer is empty due +to mismatched CALLs/RETs or returning from a deep call stack, the branch +predictor can fall back to using the Branch Target Buffer (BTB). If a +user forces a BTB collision then the RET can speculatively branch to a +user-controlled address. + +* Note that RSB filling doesn't fully mitigate this issue. If there + are enough unbalanced RETs, the RSB may still underflow and fall back + to using a poisoned BTB entry. + +* On context switch, user->user underflow attacks are mitigated by the + conditional IBPB [#cond-ibpb]_ on context switch which effectively + clears the BTB: + + * "The indirect branch predictor barrier (IBPB) is an indirect branch + control mechanism that establishes a barrier, preventing software + that executed before the barrier from controlling the predicted + targets of indirect branches executed after the barrier on the same + logical processor." [#intel-ibpb-btb]_ + +* On context switch and VMEXIT, user->kernel and guest->host RSB + underflows are mitigated by IBRS or eIBRS: + + * "Enabling IBRS (including enhanced IBRS) will mitigate the "RSBU" + attack demonstrated by the researchers. As previously documented, + Intel recommends the use of enhanced IBRS, where supported. This + includes any processor that enumerates RRSBA but not RRSBA_DIS_S." + [#intel-rsbu]_ + + However, note that eIBRS and IBRS do not mitigate intra-mode attacks. + Like RRSBA below, this is mitigated by clearing the BHB on kernel + entry. + + As an alternative to classic IBRS, call depth tracking (combined with + retpolines) can be used to track kernel returns and fill the RSB when + it gets close to being empty. + +Restricted RSB Alternate (RRSBA) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Some newer Intel CPUs have Restricted RSB Alternate (RRSBA) behavior, +which, similar to RSBA described above, also falls back to using the BTB +on RSB underflow. The only difference is that the predicted targets are +restricted to the current domain when eIBRS is enabled: + +* "Restricted RSB Alternate (RRSBA) behavior allows alternate branch + predictors to be used by near RET instructions when the RSB is + empty. When eIBRS is enabled, the predicted targets of these + alternate predictors are restricted to those belonging to the + indirect branch predictor entries of the current prediction domain. + [#intel-eibrs-rrsba]_ + +When a CPU with RRSBA is vulnerable to Branch History Injection +[#bhi-paper]_ [#intel-bhi]_, an RSB underflow could be used for an +intra-mode BTI attack. This is mitigated by clearing the BHB on +kernel entry. + +However if the kernel uses retpolines instead of eIBRS, it needs to +disable RRSBA: + +* "Where software is using retpoline as a mitigation for BHI or + intra-mode BTI, and the processor both enumerates RRSBA and + enumerates RRSBA_DIS controls, it should disable this behavior." + [#intel-retpoline-rrsba]_ + +---- + +References +========== + +..
