Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: comedi: niatmio16d: Fixed invalid cleanup after a failed attach operation. If the driver’s COMEDI “attach” handler function atmio16dattach returns an error, the COMEDI core will call the driver’s “detach” handler function...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs: The code checks contexts-nr before accessing contextsarr0. Multiple sysfs command paths dereference contextsarr0 without first verifying that kdamond-contexts-nr == 1. A user can set nrcontexts to 0 via sysfs whil...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mmc: mmcspi: fixed error handling in mmcspiprobe If mmcaddhost fails, there is no need to call mmcremovehost; otherwise, it may cause a null-ptr-deref issue, due to deleting a device that was not properly added in mmcremovehost. ...

Astra Linux – Vulnerability in libarchive

In libarchive before version 3.6.2, the software does not check for an error after calling the calloc function. This function may return a NULL pointer if it fails, leading to a NULL pointer being dereferenced. NOTE: The discoverer cites this CWE-476 issue, but third parties dispute its impact on...
