kernel: Linux kernel (qla2xxx): Double free vulnerability leads to denial of service and potential privilege escalation.

A flaw was found in the Linux kernel's qla2xxx block SCSI generic bsg interface. This vulnerability, a double free, occurs because certain vendor-specific handlers incorrectly call the bsgjobdone function on both successful and failed operation paths. A local user could exploit this to trigger...

freerdp: FreeRDP: Denial of Service via double free vulnerability during disconnect

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This double free vulnerability occurs during the cleanup process when a remote desktop session disconnects. Specifically, if a title allocation fails, a pointer to an application window is freed but not removed fro...
