Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock occurs in the Linux kernel when sriov del vfs is called as part of pci stop and remove bus device. This happens because the system recursively attempts to acquire the pci resc...

filelock has a TOCTOU race condition which allows symlink attacks during lock file creation

Impact A Time-of-Check-Time-of-Use TOCTOU race condition allows local attackers to corrupt or truncate arbitrary user files through symlink attacks. The vulnerability exists in both Unix and Windows lock file creation where filelock checks if a file exists before opening it with OTRUNC. An attack...

CVE-2025-68304

CVE-2025-68304 concerns the Linux kernel Bluetooth path. The issue occurs in the RX path of HCI protocol handling where the hci_conn object may be concurrently modified/deleted while still being looked up, enabling a use-after-free in certain code paths. The bug was addressed by moving the lookup...
