CVE-2026-79603

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 a PV guest can modify an already scrubbe...

CVE-2026-72889

A flaw was found in Net::OAuth for Perl. A remote attacker can exploit this vulnerability by manipulating the signature algorithm used for verification. By specifying a weaker algorithm, such as HMAC-SHA1 or HMAC-SHA256, in the incoming message, the attacker can force the system to use a...

CVE-2026-79603

Xen hypervisor x86 PV (para-virtualized) guests can free memory pages while retaining a stale TLB entry pointing to them. Xen issues a TLB flush only when a freed page is re-used , not at the time of freeing. Because the page can be scrubbed (zeroed or reassigned) before that TLB flush occurs, a ...
