CVE-2026-74718

This vulnerability affects the Linux kernel devlink subsystem. In devlink_nl_reload_doit(), a call to devlink_netns_get() acquires a reference to a network namespace. When the requested namespace differs from the current one and the reload action is not DRIVER_REINIT, the function returns -EOPNOT...

CVE-2026-74691

CVE-2026-74691 is a teardown ordering bug in the Linux kernel Thunderbolt network driver (net: thunderbolt / tbnet). The driver stops its DMA rings and frees frame buffers before deactivating the high-speed DMA paths, but the setup path was previously fixed to enable paths last. Teardown was neve...

CVE-2026-74692

A TOCTOU race condition in the Linux kernel's net/smc module allows a remote attacker to trigger kernel memory exhaustion. The function smc_listen_out() reads the listener's socket state without holding the listener lock, then acquires the lock only afterward. This window lets smc_close_active() ...

CVE-2026-74689

A slab-out-of-bounds read vulnerability in the Linux kernel's ATM (Asynchronous Transfer Mode) network protocol, specifically in vcc_setsockopt(). The root cause is an ineffective optlen check: when __SO_LEVEL_MATCH evaluates to false, the length validation is short-circuited and bypassed. Additi...

CVE-2026-74684

This vulnerability is a NULL pointer dereference in the Linux kernel's net: tap module, specifically in tap_get_user_xdp().
