    affected < 4.17.1_04-1.1fixed 4.17.1_04-1.1

    Mishandling of guest SSBD selection on AMD hardware The current logic to set SSBD on AMD Family 17h and Hygon Family 18h processors requires that the setting of SSBD is coordinated at a core level, as the setting is shared between threads. Logic was introduced to keep track of ho

    affected < 4.17.0_06-1.1fixed 4.17.0_06-1.1

    x86: speculative vulnerability in 32bit SYSCALL path Due to an oversight in the very original Spectre/Meltdown security work (XSA-254), one entrypath performs its speculation-safety actions too late. In some configurations, there is an unprotected RET instruction which can be att

  • CVE-2022-42330Jan 26, 2023
    affected < 4.17.0_04-1.1fixed 4.17.0_04-1.1

    Guests can cause Xenstore crash via soft reset When a guest issues a "Soft Reset" (e.g. for performing a kexec) the libxl based Xen toolstack will normally perform a XS_RELEASE Xenstore operation. Due to a bug in xenstored this can result in a crash of xenstored. Any other use of

    affected < 4.17.0_02-1.1fixed 4.17.0_02-1.1

    lock order inversion in transitive grant copy handling As part of XSA-226 a missing cleanup call was inserted on an error handling path. While doing so, locking requirements were not paid attention to. As a result two cooperating guests granting each other transitive grants can c

  • CVE-2022-33746Oct 11, 2022
    affected < 4.17.0_02-1.1fixed 4.17.0_02-1.1

    P2M pool freeing may take excessively long The P2M pool backing second level address translation for guests may be of significant size. Therefore its freeing may take more time than is reasonable without intermediate preemption checks. Such checking for the need to preempt was so

  • CVE-2022-33745Jul 26, 2022
    affected < 4.16.1_02-3.1fixed 4.16.1_02-3.1

    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 cha

  • CVE-2022-21123Jun 15, 2022
    affected < 4.16.1_02-3.1fixed 4.16.1_02-3.1

    affected < 4.16.1_02-3.1fixed 4.16.1_02-3.1

    x86 pv: Race condition in typeref acquisition Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to maintain invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables; updates

  • CVE-2022-26363Jun 9, 2022

    race in VT-d domain ID cleanup Xen domain IDs are up to 15 bits wide. VT-d hardware may allow for only less than 15 bits to hold a domain ID associating a physical device with a particular domain. Therefore internally Xen domain IDs are mapped to the smaller value range. The clea
