kernel: smb/client: fix memory leak in smb2_open_file()

A memory leak flaw was found in the Linux kernel's CIFS/SMB client. In the smb2openfile function, request buffers are not properly freed when performing direct I/O writes to a read-only SMB share. This causes slab cache objects to remain allocated, which can prevent the cifs module from unloading...

kernel: ibmvnic: Don't reference skb after sending to VIOS

In the Linux kernel, the following vulnerability has been resolved: ibmvnic: Don't reference skb after sending to VIOS Previously, after successfully flushing the xmit buffer to VIOS, the txbytes stat was incremented by the length of the skb. It is invalid to access the skb memory after sending t...
