CVE-2026-80643

A flaw was found in the Linux kernel's EDAC/igen6 driver. When this driver is unloaded, a missing 'release' function for memory controller devices can lead to a system call trace. This issue indicates a system error and could potentially result in system instability or a denial of service DoS...

The vulnerability of the mtk_smi_larb_remove() function in the drivers/memory/mtk-smi.c module of the memory controller driver for the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the mtksmilarbremove function in the driver/memory/mtk-smi.c file of the memory driver for the Linux operating system’s kernel is related to improper memory release memory leak. Exploiting this vulnerability can allow an attacker to cause a system failure...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: EDAC/bluefield: Fixed potential integer overflows. The 64-bit argument for the “get DIMM info” SMC call consists of memctrlidx, which is left-shifted by 16 bits and OR-ed with the DIMM index. Since memctrlidx is defined as a 32-b...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: EDAC/mc: Fixed the error path ordering in edacmcalloc. When the mci-pvtinfo allocation in edacmcalloc fails, the error path will call putdevice, which will ultimately call the device’s release function. However, the initializatio...

Astra Linux – Vulnerability in Intel Microcode

Incorrect default permissions in some memory controller configurations for certain IntelR XeonR processors when using IntelR Software Guard Extensions may allow a privileged user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: sh: dma: Fixed the DMA channel offset calculation. Various SoCs from the SH3, SH4, and SH4A family, which use this driver, have different numbers of DMA channels, and these channels can be distributed across up to two DMAC...

CVE-2026-53045

CVE-2026-53045 concerns the Linux kernel memory subsystem, specifically the tegra124-emc component. The issue is that the check to determine whether DLL (Delay-Locked Loop) is enabled in the EMRS register was reversed: DLL is actually enabled when bit A0 is low. A fix to the check was applied in ...
