CVE-2026-43424
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ftcm: Fix NULL pointer dereferences in nexus handling The tpg-tpgnexus pointer in the USB Target driver is dynamically managed and tied to userspace configuration via ConfigFS. It can be NULL if the USB host sends...
CVE-2026-43424
The CVE concerns the Linux kernel USB gadget f_tcm nexus handling. The tpg->tpg_nexus pointer used by the BOT command/data paths can be NULL during race windows (before nexus is established or after it’s dropped). Dereferencing tv_nexus->tvn_se_sess without a NULL check leads to a kernel pa...
CVE-2026-43423
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: Fix atomic context locking issue The ncmsetalt function was holding a mutex to protect against races with configfs, which invokes the might-sleep function inside an atomic context. Remove the struct netdevice...
CVE-2026-43343
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fsubset: Fix unbalanced refcnt in gethfree gethalloc increments the reference count, but gethfree fails to decrement it. This prevents the configuration of attributes via configfs after unlinking the function...
CVE-2026-43342
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: frndis: Protect RNDIS options with mutex The class/subclass/protocol options are suspectible to race conditions as they can be accessed concurrently through configfs. Use existing mutex to protect these options. This...

CVE-2026-43343
CVE-2026-43343 affects the Linux kernel USB gadget f_subset code. The vulnerability stems from an unbalanced reference count: geth_alloc() increments the refcount, but geth_free() does not decrement it, which can block configuration of attributes via configfs after unlinking the function. The con...

CVE-2026-43342
CVE-2026-43342 concerns the Linux kernel USB gadget RNDIS driver (f_rndis). The issue arises from race conditions when RNDIS options (class/subclass/protocol) are accessed concurrently via configfs, enabling unsafe concurrent access. The remediation implemented is to protect these options using a...
