Dynamic Attack Surfaces: A Queue of Branching Processes

Modern attack surfaces are inherently dynamic. Vulnerabilities emerge over time and they remain exposed to exploit until defenders discover and patch them. Artificial intelligence AI amplifies these dynamics by accelerating both offensive and defensive processes, making modern cybersecurity...

Astra Linux – Vulnerability in Linux 5.15

A use-after-free flaw was discovered in the Linux kernel. When a disk is removed, the bdiunregister function is called to stop further write-back operations, and the system waits for the associated delayed tasks to complete. However, the wb inodewritebackend function may schedule bandwidth...

kernel: fs: writeback: fix use-after-free in __mark_inode_dirty()

A flaw was found in the Linux kernel. A race condition in the writeback subsystem can lead to a use-after-free vulnerability when an inode's writeback structure is concurrently switched. A local attacker with administrative privileges could trigger this flaw during writeback management operations...
