CVE-2026-98772

A flaw was found in the Linux kernel's USB serial subsystem. This flaw may result in a Denial of Service DoS due to a use-after-free vulnerability. During multiport device disconnection, a race condition allows background completion handlers to access port driver data after it has already been...

CVE-2026-98697

A flaw was found in the Linux kernel's USB serial subsystem. A race condition during USB serial driver deregistration can result in a kernel memory leak. A local user with permissions to modify driver attributes can trigger this issue by writing to the dynamic identifier interface while the drive...

CVE-2026-98695

A flaw was found in the Linux kernel's USB serial subsystem. A local user could cause a Denial of Service DoS due to a race condition between input/output control ioctl operations and device disconnection. If a USB serial device is disconnected during an active operation, the driver may attempt t...

CVE-2026-98696

A flaw was found in the Linux kernel's USB serial subsystem. A local user with administrative privileges could exploit this flaw to cause a Denial of Service DoS or memory corruption. During the unloading of a USB serial driver module, drivers are deregistered in an incorrect sequence, allowing...
