Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: soc: ti: k3-socinfo: Fixed the regmap leak that occurs during probe failures. The mmio regmap allocated during the probe never gets freed. We have switched to using the device-managed allocator, so that the regmap is released...

CVE-2026-89721

A flaw was found in the Linux kernel's phy: rockchip-samsung-dcphy component. A local attacker with access to the regmap debugfs interface could trigger an out-of-bounds read by attempting to dump registers. This occurs because the maxregister value is incorrectly set, causing the system to read...
