Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a missing bounds check in smartcardunpackreadsizealign libfreerdp/utils/smartcardpack.c:1703 allowed a malicious RDP server to crash the FreeRDP client through a reachable WINPRASSERT → abort mechanism. This...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ASoC: ops: Fixed the bounds check for sx controls. For sx controls, the semantics of the max field are not the usual one; max represents the number of steps, rather than the maximum value. This means that our check in...

Astra Linux – Vulnerability in xwayland, xorg-server

A buffer overflow vulnerability was discovered in X.Org and Xwayland. The code in XkbVModMaskText allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and will copy the data regardless of the siz...

CVE-2026-89525

A flaw was found in the Linux kernel. A local attacker could craft a malicious Universal Disk Format UDF image to trigger an out-of-bounds read vulnerability in the udfgetpblockvirt15 function. This occurs when the system attempts to read a Virtual Allocation Table VAT index equal to the entry...

CVE-2026-89610

A flaw was found in the Linux kernel's NTFS component. The mapping pairs decoder fails to verify if a run length extends beyond the volume boundary. A local attacker could exploit this by providing a malformed NTFS image with a crafted mapping pairs array. This could lead to memory corruption and...
