kernel: nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm()

A vulnerability has been identified in the Linux kernel's Network File System NFS daemon that could allow for a Denial of Service and in worst case scenario Arbitrary Code Execution. This Use-After-Free flaw arises from a race condition when the kernel handles the confirmation of an NFS client...

kernel: NFSD: Protect against send buffer overflow in NFSv2 READ

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READ Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffers into a single array of pages. This...
