CVE-2026-68369

A flaw was found in the Linux kernel's USB gadget printer driver. An attacker, by providing specific input to the printerread function, could trigger an infinite loop. This vulnerability occurs when the copytouser function fails to copy data, leading to a denial of service condition where the...

CVE-2026-68368

A flaw was found in the Linux kernel's USB gadget NCM Network Control Model driver. This vulnerability occurs because the driver fails to properly validate the boundaries of datagrams and Network Transfer Blocks NTBs supplied by a USB host. A malicious USB host can exploit this by crafting specif...

CVE-2026-68367

A flaw was found in the Linux kernel's USB gadget function ftcm. A local attacker could exploit a race condition during the teardown of a USB gadget function. This could lead to a use-after-free vulnerability, potentially causing a system crash denial of service or, in more severe cases, arbitrar...

CVE-2026-68370

A flaw was found in the Linux kernel's USB gadget dummy Host Controller Driver HCD. A race condition can occur when a shared USB request object fiforeq is prematurely reused before its completion callback has finished. This can lead to the overwriting of the callback pointer, causing a general...

CVE-2026-68088

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: dummyhcd: prevent fiforeq reuse during giveback dummyhcd embeds a single shared usbrequest dum-fiforeq that the "emulated single-request FIFO" fast-path in dummyqueue reuses for small IN transfers: it copies the...

CVE-2026-68370

CVE-2026-68370 affects the Linux kernel USB gadget dummy_hcd path. A race condition reuses a shared usb_request (fifo_req) before its completion callback finishes, allowing overwriting of the callback pointer and causing a general protection/page fault in dummy_timer. The mitigation adds a fifo_r...
