CVE-2026-54905

A flaw was found in concurrent-ruby. The Concurrent::ReentrantReadWriteLock component can incorrectly grant a write lock to a thread while other threads still hold or can acquire read locks. This occurs when a thread acquires a read lock 32,768 times, causing an internal counter to incorrectly...

CVE-2026-53323

CVE-2026-53323 affects the Linux kernel DSA conduit ethtool wrappers. The root cause is redundant locking: the conduit master’s ethtool_ops were wrapped by DSA to aggregate port stats, and an extra netdev_lock_ops()/netdev_unlock_ops() inside the DSA wrappers could deadlock. The documented remedi...
