Описание
In the Linux kernel, the following vulnerability has been resolved: ublk: santizize the arguments from userspace when adding a device Sanity check the values for queue depth and number of queues we get from userspace when adding a device.
Отчет
A missing input validation in ublk_ctrl_add_dev() in the ublk driver allows an unprivileged userspace application (if UBLK_F_UNPRIVILEGED_DEV is enabled) or a privileged user (CAP_SYS_ADMIN) to supply invalid queue_depth or nr_hw_queues values. If unchecked, these values could exceed internal limits, possibly leading to a kernel crash. Triggering this vulnerability requires either root privileges or elevated capabilities (CAP_SYS_ADMIN) unless the system is explicitly configured to allow unprivileged ublk devices, which is rare.
