kernel: tpm: Clean up TPM space after command failure

A flaw was found in the Linux kernel's Trusted Platform Module TPM driver. When a TPM command transmission fails, the driver does not properly clean up allocated resources, leading to a leak of transient handles. This resource exhaustion can result in a denial of service, making the TPM device...

kernel: virtio_pmem: add the missing REQ_OP_WRITE for flush bio

A flaw was discovered in the virtiopmem driver in the Linux kernel, where flush block I/O requests did not have the required REQOPWRITE operation code assigned before submission. Under workloads involving persistent memory block devices — for example, running mkfs.xfs on a pmem device,this omissi...
