Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Rapidio: fixed a possible UAF Use-after-Allocation when kfifoalloc fails. If kfifoalloc fails in mportcdevopen, it jumps to errfifo and simply frees priv. However, priv is still in chdev-filelist, and traversing the list may lead...

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: uacce: Fixed the handling of cdev in the cleanup path. When cdevdeviceadd fails, it internally releases the cdev memory. If cdevdevicedel is then executed, it will cause a hang error. To fix this issue, we check the return value ...

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, Linux

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fhid: fixed the lifetime of fhidg relative to cdev The embedded struct cdev does not correctly tie its lifetime to the surrounding struct fhidg. As a result, there may be a use-after-free if /dev/hidgN is kept open...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: rapidio: devices: fixed the issue where putdevice was missing in mportcdevopen. When kfifoalloc fails, the reference count of chdev-dev remains incremented. We should use putdevice&chdev-dev to decrement the reference count of...
