UBUNTU-CVE-2026-98604

In the Linux kernel, the following vulnerability has been resolved: ovpn: replace bind when learning local endpoint struct ovpnbind is published through peer-bind with RCU, but local endpoint learning updates bind-local in place under peer-lock. UDP TX reads the field without that lock. In...

UBUNTU-CVE-2026-98847

In the Linux kernel, the following vulnerability has been resolved: rtc: spear: initialize IRQ state before requesting alarm IRQ devmrequestirq enables the interrupt before it returns, so the handler may run while probe is still initializing the device. Initialize the MMIO address and spinlock...

UBUNTU-CVE-2026-98846

In the Linux kernel, the following vulnerability has been resolved: sctp: check RCVSHUTDOWN after the sendmsg connect wait sctpwaitforconnect drops the socket lock while it sleeps. An out-of-the-blue ABORT can then be processed from the socket backlog and unlink the association. If a concurrent...
