TITLE

Linux of Linux Kernel Vulnerability regarding lack of memory release after expiration in

Trust: 0.8

sources: JVNDB: JVNDB-2024-004928

DESCRIPTION

In the Linux kernel, the following vulnerability has been resolved: crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak Using completion_done to determine whether the caller has gone away only works after a complete call. Furthermore it's still possible that the caller has not yet called wait_for_completion, resulting in another potential UAF. Fix this by making the caller use cancel_work_sync and then freeing the memory safely. Linux of Linux Kernel Contains a vulnerability regarding the lack of free memory after expiration.Service operation interruption (DoS) It may be in a state. The RUGGEDCOM RST2428P is a Layer 2 Ethernet switch based on the SINEC operating system with up to 28 non-blocking interfaces. SCALANCE X switches are used to connect industrial components such as programmable logic controllers (PLCs) or human-machine interfaces (HMIs). Multiple vulnerabilities in third-party components of Siemens' SINEC OS could allow attackers to gain control of the server
