CVE-2026-72483

A flaw was found in the Linux kernel's USB host driver, specifically in the max3421hubcontrol function. A malicious userspace task with access to the root hub can trigger a shift-out-of-bounds vulnerability by issuing a crafted USBDEVFSCONTROL ioctl. This can lead to arbitrary bit corruption of t...

CVE-2026-72483

In the Linux kernel, the max3421 USB hub control path (max3421_hub_control) improperly shifted port_status by 1 <= 32, this shift can cause shift-out-of-bounds behavior, leading to arbitrary bit corruption of port_status and potential bypass of internal checks. The fix rejects requests whose v...

CVE-2021-47582

In the Linux kernel, the following vulnerability has been resolved: USB: core: Make doproccontrol and doprocbulk killable The USBDEVFSCONTROL and USBDEVFSBULK ioctls invoke usbstartwaiturb, which contains an uninterruptible wait with a user-specified timeout value. If timeout value is very large...
