CVE-2026-73282

A flaw was found in OpenSSH. A use-after-free vulnerability exists in the ssh client when handling concurrent remote-forwarding operations. This can occur if a remote forwarding is added via the local session multiplexing socket while a remote forwarding open request is pending with the server. A...

CVE-2026-72024

A flaw was found in the mac802154 component of the Linux kernel. When network interfaces are removed, the system incorrectly manages memory, which can cause a program to try and use memory that is no longer available or has been corrupted. This vulnerability could lead to system instability or a...

CVE-2026-72486

A flaw was found in the Linux kernel's mtk-adsp mailbox driver. During device teardown, if the Sound Open Firmware SOF audio driver fails to initialize, a timing issue can occur where an interrupt is processed after the associated memory has been released. This Use-After-Free UAF vulnerability ca...

CVE-2026-72472

A flaw was found in the Network File System NFS component of the Linux kernel. Inadequate synchronization during the traversal of the file lock list can lead to a use-after-free UAF vulnerability. This occurs when certain functions release file locks prematurely while iterating, potentially...

CVE-2026-72411

A flaw was found in the Linux kernel's mxl862xx Digital Subscriber Line DSA driver. An issue during the driver's teardown process, specifically when handling MDIO CRC errors, can lead to a use-after-free vulnerability. This allows the system to attempt to access memory that has already been...

CVE-2026-72012

A flaw was found in the Linux kernel's tracing/osnoise component. When unregistering a tracer instance, the system failed to call synchronizercu, a mechanism for synchronizing read-copy-update RCU operations. This oversight could allow RCU readers to access memory that has already been freed,...
