Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: mdio: Fixed an unbalanced fwnode reference count in mdiodevicerelease. There is a warning report regarding a refcount leak when probing the mdio device: OF: Error: Memory leak; the expected refcount was 1 instead of 2. The...

kernel: drm/i915/gt: fix refcount underflow in intel_engine_park_heartbeat

A flaw was found in the Linux kernel's i915 graphics driver. A race condition exists between the heartbeat worker and intelengineparkheartbeat functions when releasing an engine request. This can lead to a reference count refcount underflow, resulting in a use-after-free vulnerability. A local...

kernel: net: qrtr: fix refcount saturation and potential UAF in qrtr_port_remove

A flaw was found in the Linux kernel's qrtr network subsystem. A race condition exists in the qrtrportremove function where the socket reference count is decremented prematurely. This allows a concurrent reader to access a socket whose reference count has dropped to zero, potentially leading to a...
