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...

CVE-2026-80659

CVE-2026-80659 is a deadlock in the Linux kernel's vub300 MMC/USB driver. When a command response times out, __vub300_command_response() synchronously resets the USB device while vub300_cmndwork_thread() still holds cmd_mutex; the reset path re-enters the driver via vub300_pre_reset() and attempt...

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...
