kernel: Kernel: Privilege escalation via uninitialized data in vmci transport packet

A flaw was found in the Linux kernel's vsock/vmci component. A local attacker with low privileges could exploit a vulnerability where the vmcitransportpacket structure is not properly cleared during initialization. This can lead to the use of uninitialized data, potentially allowing for informati...

kernel: Linux kernel: RDMA/rxe use-after-free vulnerability leading to potential arbitrary code execution

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe component. This use-after-free vulnerability occurs in the rxecreatecq function. When the rxecqfrominit function fails, the subsequent call to rxecleanup attempts to free memory resource...
