Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Viawdt: fixed a critical boot hang caused by unnamed resource allocation. The VIA watchdog driver uses allocateresource to reserve a MMIO region for the watchdog control register. However, the allocated resource was not given a...

CVE-2026-97970

A flaw was found in the Linux kernel's MSC313e watchdog driver. A local user or an unconfigured clock condition during device initialization can cause the driver to encounter a zero clock rate. Because the driver fails to validate this value before using it in a division operation, a...

CVE-2026-97969

A flaw was found in the Linux kernel's Mstar MSC313e watchdog driver. When adjusting the watchdog timeout setting, the driver unconditionally activates the timer even if the watchdog device is currently inactive. A local user with access to configure the watchdog device could exploit this flaw to...

CVE-2026-97504

A flaw was found in the Linux kernel's Lenovo SE10 watchdog driver. Improper error handling during device initialization fails to clear a platform device pointer if registration fails, resulting in a use-after-free condition. A local user could exploit this vulnerability to cause a Denial of...

CVE-2026-98121

A flaw was found in the Linux kernel's Mstar MSC313e watchdog driver. The driver fails to properly set platform device data during device initialization. Consequently, when system power management routines attempt to access this data during suspend or resume operations, a NULL pointer dereference...

PT-2026-98123

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free and resource leak risk exists in the lenovo se10 wdt watchdog driver. The issue occurs when the se10 pdev variable is not properly nullified, potentially allowing the...

CVE-2026-74687

A flaw was found in the Linux kernel, specifically within the at91sam9wdt watchdog timer driver. During the driver's teardown process, the at91ping function could rearm the watchdog timer. However, the timerdelete function does not prevent this, resulting in a use-after-free vulnerability where t...

SUSE CVE-2026-74687

In the Linux kernel, the following vulnerability has been resolved: watchdog: at91sam9wdt: prevent timer rearm during teardown at91ping rearms the watchdog timer from its callback. timerdelete neither waits for a running callback nor prevents it from rearming the timer, so probe failure or driver...

CVE-2026-74687

This vulnerability affects the Linux kernel 's at91sam9_wdt watchdog driver. The root cause is a use-after-free : the at91_ping() callback rearms the watchdog timer, but timer_delete() neither waits for a running callback nor prevents rearm, so during probe failure or driver removal the timer can...

PT-2026-69756

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A division by zero occurs in the airoha watchdog driver when the clock frequency is zero. This happens because the clk get rate function can return 0 if the clock provider is unmanaged o...

The vulnerability of the watchdog_cdev_register() function in the drivers/watchdog/watchdog_dev.c module, which supports Linux kernel watchdog timers, allows a malicious actor to trigger a service failure.

The vulnerability of the watchdogcdevregister function in the drivers/watchdog/watchdogdev.c module, which supports the Linux kernel watchdog timer, is related to improper memory release. Exploiting this vulnerability could allow an attacker to trigger a service failure...

CVE-2025-71114

CVE-2025-71114 relates to the VIA watchdog driver in the Linux kernel. The driver uses allocate_resource() to reserve a MMIO region for the watchdog control register, but the resource lacked a name, causing the kernel resource tree to contain a entry under /proc/iomem on x86. During boot, this u...
