insufficient TLB flush for x86 PV guests in shadow mode For migration as well as to work around kernels unaware of L1TF (see XSA-273), PV guests may be run in shadow paging mode. To address XSA-401, code was moved inside a function in Xen. This code movement missed a variable changing meaning / value between old and new code positions. The now wrong use of the variable did lead to a wrong TLB flush condition, omitting flushes where such are necessary. Un vaciado insuficiente del TLB para huéspedes x86 PV en modo de sombra Para la migración, así como para trabajar en torno a los kernels que no son conscientes de L1TF (véase XSA-273), los huéspedes PV pueden ejecutarse en modo de paginación de sombra. • http://www.openwall.com/lists/oss-security/2022/07/26/2 http://www.openwall.com/lists/oss-security/2022/07/26/3 http://xenbits.xen.org/xsa/advisory-408.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HUFIMNGYP5VQAA6KE3T2I5GW6UP6F7BS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MYI3OMJ7RIZNL3C6GUWNANNPEUUID6FM https://www.debian.org/security/2022/dsa-5272 https://xenbits.xenproject.org/xsa/advisory-408.txt •
