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

A use-after-free flaw was discovered in the Linux kernel’s SGI GRU driver. This flaw arises from the way the grufileunlockedioctl function is called by the user, resulting in a failure in the grucheckchipletassignment function. This flaw allows a local user to cause a system crash or potentially...

Astra Linux – Vulnerability in Linux 5.15

A out-of-bounds memory read flaw was discovered in the parseleasestate function within the KSMBD implementation of the in-kernel Samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command along with a malformed payload to KSMBD, due to a lack of checks on the NameOffset...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Create the debugfs ttmresourcemanager entry only if needed The driver creates /sys/kernel/debug/dri/0/mobttm even when the corresponding ttmresourcemanager is not allocated. This leads to a crash when trying to read...

In the Linux kernel, the following vulnerability has been resolved: drm: A use-after-free issue in drmgetunique has been fixed. There is a time-of-check-to-time-of-use error in drmgetunique, caused by retrieving fpriv-master before locking the device’s master mutex. An example of this error can b...

Astra Linux – Vulnerability in Linux 5.15

A NULL pointer dereference flaw was discovered in the Linux kernel’s drivers/gpu/drm/msm/msmgemsubmit.c code, specifically in the submitlookupcmds function. This flaw occurs because there is no check on the return value of kmalloc. This issue allows a local user to crash the system...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: i40e: Fixed NULL pointer dereferencing in i40edbgdumpdesc. When attempting to dump VFs using debugfs, a crash occurred due to NULL pointer dereferencing in i40edbgdumpdesc. A check was added to i40edbgdumpdesc to ensure that the...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-48 and 7.1.2-23, when using LZMA compression in the MIFF encoder, an out-of-bounds write vulnerability could occur due to a missing check. This issue has been fixed in versions...
