UBUNTU-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...

A guest with a PCI device assigned that has at least a BAR on the IO port space can trigger a BUG in Xen...
UBUNTU-CVE-2026-62437
When guests are terminated, various pieces of cleanup need carrying out. The cleaning up of PCI devices which were assigned to guests, and the associated removal of tracking structures for IRQs used by the devices occurs relatively early in the process. Unfortunately after that point the guest...

UBUNTU-CVE-2026-86469
A flaw was found in GLib2. When gfilereplace is used with GFILECREATEREPLACEDESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the...
UBUNTU-CVE-2026-18355
A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, the wrapped-record length read from the wire is validated only against an upper bound. A small wire length 0, 1, or 2 produces an encryptedbuffercount below the already-consumed...
