CVE-2026-80659

A flaw was found in the Linux kernel's vub300 driver. When the vub300cmndworkthread function holds a command mutex and a command response times out, the device reset path attempts to re-acquire the same mutex recursively. This recursive locking can lead to a deadlock, causing a Denial of Service...

The vulnerability of the vub300_disconnect() function in the drivers/mmc/host/vub300.c module of the MMC/SD/SDIO card driver for the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the vub300disconnect function in the drivers/mmc/host/vub300.c module of the MMC/SD/SDIO card driver for the Linux operating system is related to the repeated use of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2026-72073

A flaw was found in the Linux kernel's vub300 driver, which manages MultiMediaCard MMC controllers. A race condition can occur during the driver's probe failure path. If the mmcaddhost function fails after an inactivity timer has been armed, a use-after-free vulnerability can arise. This could...

CVE-2026-31651

A flaw was found in the Linux kernel's mmc: vub300 driver. This vulnerability allows a local attacker to trigger a NULL-pointer dereference or use-after-free condition during device disconnection. Successful exploitation could lead to a system crash, resulting in a denial of service...

CVE-2026-31650

A flaw was found in the vub300 driver within the Linux kernel. This vulnerability is a memory management issue where the system attempts to use memory that has already been freed, known as a 'use-after-free' error. This can happen when the driver is disconnected, potentially leading to system...

CVE-2026-31650

The CVE concerns the Linux kernel mmc vub300 driver. The root cause is a use-after-free risk from device-managed controller allocation and a lifetime tie to the parent USB device rather than the interface, which can cause memory leaks if the driver is unbound without a disconnect. A last referenc...
