The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:6460 advisory.
- hw: cpu: incomplete clean-up of multi-core shared buffers (aka SBDR) (CVE-2022-21123)
- hw: cpu: incomplete clean-up of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125)
- hw: cpu: incomplete clean-up in specific special register write operations (aka DRPW) (CVE-2022-21166)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

(CVE-2022-23825)\n\n - x86 pv: Race condition in typeref acquisition Xen maintains a type reference count for pages, in addition\n to a regular reference count. This scheme is used to maintain invariants required for Xen's safety, e.g.\n PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately,\n the logic for acquiring a type reference has a race condition, whereby a safely TLB flush is issued too\n early and creates a window where the guest can re-establish the read/write mapping before writeability is\n prohibited. (CVE-2022-26362)\n\n - x86 pv: Insufficient care with non-coherent mappings T[his CNA information record relates to multiple\n CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen maintains a type\n reference count for pages, in addition to a regular reference count. This scheme is used to maintain\n invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables;\n updates need auditing by Xen. Unfortunately, Xen's safety logic doesn't account for CPU-induced cache non-\n coherency; cases where the CPU can cause the content of the cache to be different to the content in main\n memory. In such cases, Xen's safety logic can incorrectly conclude that the contents of a page is safe.\n (CVE-2022-26363, CVE-2022-26364)\n\n - Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution\n under certain microarchitecture-dependent conditions. (CVE-2022-29900)\n\n - insufficient TLB flush for x86 PV guests in shadow mode For migration as well as to work around kernels\n unaware of L1TF (see XSA-273), PV guests may be run in shadow paging mode. To address XSA-401, code was\n moved inside a function in Xen. This code movement missed a variable changing meaning / value between old\n and new code positions. The now wrong use of the variable did lead to a wrong TLB flush condition,\n omitting flushes where such are necessary.
