CVE-2026-62430

A flaw was found in Xen. This vulnerability allows a guest operating system to read data beyond its intended memory boundaries, potentially leading to information disclosure. The issue arises from improper synchronization during access to the CMOS Complementary Metal-Oxide-Semiconductor memory. A...

DEBIAN-CVE-2026-6879

Element.findall and fully-consumed Element.iterfind exhibit On^2 time complexity when using XPath index predicates e.g. 1, last, last-N on XML documents with many same-tag siblings. Element.find is only affected when the first match is near the end of the sibling list, such as with last or...

CVE-2026-6879

CVE-2026-6879 affects Python's xml.etree.ElementTree path handling. Element.findall() and fully-consumed Element.iterfind() exhibit O(n^2) time when using XPath index predicates like [1], [last()], or [last()-N] on documents with many siblings of the same tag. Element.find() is affected only when...

CVE-2026-62430

Accesses to the CMOS memory contents are done using an indirect IO port pair. Therefore Xen needs to cache the guest chosen index, and one of the usages of the index didn't take the necessary locking to avoid concurrent changes. As a result, a guest could change the index after it being checked,...

CVE-2026-62430

CVE-2026-62430 affects the Xen hypervisor (x86) in the vRTC emulation. Accesses to CMOS memory use an indirect IO port pair; Xen caches the guest-selected index but one usage of the index lacks proper locking, allowing a guest to change the index after it is checked and trigger a subsequent out-o...
