Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/sched: actct: fix ref leak when switching zones When switching zones or network namespaces without performing a ct clear between them, a reference to the old ct entry is still leaked. This occurs because tcfctskbnfctcached...

CVE-2026-52904

CVE-2026-52904 affects the Linux kernel's DRM Nouveau NVKM path. When aperture_remove_conflicting_pci_devices() fails, nvkm_device_pci_new() could leak the device wrapper and pci_enable_device() reference. The fix redirects to the existing fail_nvkm path so nvkm_device_del() runs and balances res...
