gnttab: cache-flush handling may cause page reference leak
With its original introduction, GNTTAB_cache_flush was made available uniformly. XSA-232 (CVE-2017-14318) then covered an omitted NULL pointer check, yet the addition of that check failed to adjust the subsequent error path. That error path fails to drop a pa…

VMX: VMentry failure with branch tracing and blocked states

grant-table: double version change race
XSA-501 was about issues with v1 -> v2 and v2 -> v1 changes racing certain other grant table operations. Sadly a v2 -> v1 -> v2 change has yet another effect which wasn't accounted for: During the first change, status pages would be freed. During the second c…

x86/AMD: ineffectual Zenbleed workaround
The workaround for XSA-433 (Zenbleed, CVE-2023-20593) was later re-worked to better integrate with other manipulations of the same MSR. In this rework an inverted conditional was introduced, resulting in the workaround to not be applied when needed and vice v…

Unconditionally do TLB flushing ahead of page scrubbing
x86 PV guests can free memory pages while still keeping a stale TLB entry pointing to them. A TLB flush is only issued by Xen (if needed) when the page is re-used. Since it's possible for the page to be scrubbed ahead of the TLB flush, there's a window where …
