Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Media: i2c: ar0521: Use the CANCSLEEP variant of the gpiodsetvalue function. If we use GPIO reset from the I2C port expander, we must use the CANCSLEEP variant of GPIO functions. This was not done in the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/slab: makefreekfree should accept error pointers. Currently, if an automatically freed allocation is an error pointer, it can lead to a crash. An example of this is in the function wm831x gpiodbgshow. c 171 char label freekfre...

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 5.10

In the Linux kernel, the following vulnerabilities have been resolved: spi-rockchip: Fixed out-of-bounds access to registers. Do not write code related to native chip selection for GPIO chip selections. GPIOs can be numbered much higher than native CS. Moreover, this approach doesn’t make any sen...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: reset: gpio: fix double-free in resetaddgpioauxdevice error path. When auxiliarydeviceadd fails, resetadd gpioauxdevice calls auxiliarydeviceuninitadev. The device release callback resetgpioauxdevicerelease frees adev, but the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: gpio: loongson-64bit: Fixed an incorrect NULL check after devmkcalloc Fixed an incorrect NULL check in loongsongpioinitirqchip. The function checks chip-parent instead of chip-irq.parents...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: gpio: mockup: Fixed a NULL pointer dereferencing issue when removing debugfs. We now remove the debugfs entries of the device when unbinding the driver. This now causes a NULL-pointer dereferencing issue at the end of the module,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Regulator: bq257xx: Fixed the issue of a reference leak on the device node in bq257xxregdtparsegpio. In bq257xxregdtparsegpio, if it fails to obtain a sub-child node, it returns without calling nodeputchild, resulting in a...

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 – Vulnerability in Linux 5.10

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. It should be freed during the error handling process...

Astra Linux – Vulnerability in Linux 5.10

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 is now...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: pinctrl: nuvoton: wpcm450: fix an out-of-bounds write issue. The write operation to ‘pctrl-gpiobank’ occurs before the check for the validity of the GPIO index, which may lead to an out-of-bounds write. This issue was detected 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, Linux

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, 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 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 in Linux 5.10

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 is only used if the debounce timer is not used...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: gpio: Restrict the use of GPIO chip IRQ members before initialization. The IRQ members of the GPIO chip are exposed before they can be fully initialized, which leads to race conditions. One such issue was observed with the...
