In the Linux kernel, the following vulnerability has been resolved: hwmon: gpiofan Fix for out-of-bounds access to arrays The driver does not check whether the cooling state passed to gpiofansetcurstate exceeds the maximum cooling state stored in fandata-numspeeds. Since the cooling state is late...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: media: uvcvideo: Fixed a memory leak in uvcgpioparse Previously, the unit buffer was allocated before checking the IRQ for privacy-related GPIO signals. If an error occurred, the unit buffer could be leaked. The issue was fixed b...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: serial: sc16is7xx: The GPIO controller is set up later in the probe function. The GPIO controller component of the sc16is7xx driver is also set up too early, which can lead to a race condition where another device attempts to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: serial: mctrlgpio: The disablems function has been split into sync and nosync APIs. The following issue was observed on the SAMA5D27 platform using the atmelserial: BUG: A sleeping function was called from an invalid context at...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: gpio: amd8111: Fixed the issue with the reference count leak of PCI devices The function foreachpcidev is implemented through pcigetdevice. The comment accompanying pcigetdevice states that it will increase the reference count...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: pinctrl: mediatek: fixed a global-out-of-bounds issue When the eint virtual eint number is greater than the gpio number, it may cause a ‘desceintn’ size global-out-of-bounds issue...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: irqchip/qcom-mpm: This issue prevents crashes when attempting to handle non-wake GPIOs. On Qualcomm chipsets, not all GPIOs are wake-up capable. These GPIOs do not have a corresponding MPM pin and should not be handled within the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: media: i2c: ar0521: Use the CANSLEEP version of gpiodsetvalue If we use GPIO reset from the I2C port expander, we must use the CANSLEEP variant of GPIO functions. This was not done in the ar0521poweron/ar0521poweroff functions...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: gpio: mockup: Fixed potential resource leakage when registering a chip. If the creation of a software node fails, the locally allocated string array remains unleased. This issue has been addressed by releasing the resource upon a...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: gpiolib: cdev: Fix use-after-free in lineinfochangednotify The use-after-free issue occurs as follows: When the GPIO chip device file is closed by invoking gpiochrdevrelease, the watchedlines object is freed by bitmapfree. Howeve...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: nvmem: core: fix cleanup after devsetname If devsetname fails, we may leak nvmem-wpgpio because the cleanup does not handle it properly. While a minimal fix would be to add the gpiodput call, we can improve the situation by...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: gpio: mvebu: fixed the irq domain leak. Uwe Kleine-König pointed out that we still have one resource leak in the mvebu driver, which is triggered when the driver is detached. We will address this issue by implementing a custom...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: gpio: wcd934x – Fixed the out-of-bounds shift error. The bit mask for pins 0 to 4 is actually BIT0 to BIT4, but we ended up using BITn – 1, which is incorrect. This issue was caught by the UBSAN check. UBSAN: Out-of-bounds shi...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: gpio: Prevent potential speculation leaks in gpiodevicegetdesc The userspace may trigger a speculative read of an address outside the gpio descriptor array. Users can do this by calling gpioioctl with an offset that is out of...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys – cancels delayed work only in case of GPIO. The gpiokeys module can accept gpios or interrupts. The module initializes delayed work only in case of gpios, and it is only used if the debounce timer is not used...
