In the Linux kernel, the following vulnerability has been resolved: tcp: fix stale per-CPU tcptwisn leak enabling ISN prediction Blamed commit moved the TIMEWAIT-derived ISN from the skb control block to a per-CPU variable, assuming the value would always be consumed by tcpconnrequest for the sam...

DEBIAN-CVE-2026-63996

In the Linux kernel, the following vulnerability has been resolved: ethtool: cmis: require exact CDB reply length Malicious SFP module could respond with rpllen longer than what cmiscdbprocessreply expected, leading to OOB writes. Malicious HW is a bit theoretical but some modules may just be bug...

DEBIAN-CVE-2026-63974

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Set HCICMDDRAINWORKQUEUE during device close Since hcidevclosesync can now be called during the reset path, we should also set HCICMDDRAINWORKQUEUE. This avoids queuing timeouts while the hdev workqueue is bei...
