In the Linux kernel, the following vulnerability has been resolved: net: phylink: record the PHY only once bringup cannot fail phylinkbringupphy stores the PHY in pl-phydev before its last fallible step: on a MAC whose phylink ops implement LPI, phyeeerxclockstop can fail with a real MDIO error...

UBUNTU-CVE-2026-98564

In the Linux kernel, the following vulnerability has been resolved: net: dsa: mt7530: leave the MDIO IRQ mappings to regmap-irq mt7530removecommon disposes the per-PHY interrupt mappings from .remove, but the regmap-irq chip that owns the domain is devm-registered, so its parent interrupt is only...

UBUNTU-CVE-2026-98583

In the Linux kernel, the following vulnerability has been resolved: nfc: nfcmrvl: validate helper command length before pull The firmware download receive path removes the NCI data header and reads the helper command before validating the remaining packet length. A short frame can therefore reach...

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: stop Tx NAPI before disabling the queues bcmgenetnetifstop and the Wake-on-LAN branch of bcmgenetsuspend both disable the Tx queues first and stop Tx NAPI several steps later. A completion in flight calls...

UBUNTU-CVE-2026-98611

In the Linux kernel, the following vulnerability has been resolved: bpf: Check params size before reading reserved fields bpfcryptoctxcreate is a kfunc whose second argument is declared with the sz annotation, so the verifier only guarantees that paramssz bytes of params are valid. The function...

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...
