CVE-2026-72411

The CVE-2026-72411 issue affects the Linux kernel’s DSA mxl862xx code. A use-after-free could occur when handling an MDIO CRC error: mxl862xx_crc_err_work_fn() iterates DSA ports and closes CPU conduits, while mxl862xx_remove() unregisters the switch and cancels the work. If CRC error work runs a...

CVE-2026-72125

In CVE-2026-72125, the Linux kernel’s CAN isotp implementation had a use-after-free race with NETDEV_UNREGISTER. During unregister, the bound net_device could be unlisted from the ifindex hash before the NETDEV_UNREGISTER notifier runs, allowing isotp_release() to free a socket while isotp_notify...
