CVE-2026-63905

A flaw was found in the Linux kernel's USB/IP Virtual USB Device Controller vudc component. A race condition exists in the vudcremove function, which can lead to a use-after-free vulnerability. This occurs when the system attempts to free a data structure while a timer within it is still active o...

CVE-2026-63904

A flaw was found in the Linux kernel's USB Test and Measurement Class USBTMC driver. This vulnerability occurs because the driver does not properly verify the size of incoming notification messages, specifically failing to ensure that required two-byte headers are present. An attacker could explo...

CVE-2026-63896

A flaw was found in the Linux kernel's USB gadget composite driver. A remote attacker, acting as a malicious USB host, could send a specially crafted GETURL request. This request, with a small wLength value, triggers an integer underflow when calculating the buffer length for a memory copy...

CVE-2026-63928

A flaw was found in the Linux kernel's USB serial omninet driver. A malicious Universal Serial Bus USB device could exploit this by reporting a smaller maximum packet size than anticipated. This action would cause the system to allocate undersized data buffers, leading to memory corruption. Such...
