kernel: SUNRPC: double free xprt_ctxt while still in use

A flaw was addressed in the Linux kernel’s SUNRPC implementation affecting deferred RPC request handling. When an RPC request is deferred, the internal rqxprtctxt pointer is moved from the active service request to a deferred request structure. Under certain rare conditions where a request is...

kernel: NFSv4: Don't hold the layoutget locks across multiple RPC calls

In the Linux kernel, the following vulnerability has been resolved: NFSv4: Don't hold the layoutget locks across multiple RPC calls When doing layoutget as part of the open compound, we have to be careful to release the layout locks before we can call any further RPC calls, such as setattr. The...

kernel: rxrpc: Fix timeout of a call that hasn't yet been granted a channel

A NULL pointer dereference flaw was found in the Linux kernel's RxRPC/AFS networking stack. When making an AFS call, the call timer can expire before a connection is assigned if the call gets stalled waiting for a connection. This causes a NULL pointer dereference in rxrpcalloctxbuf when attempti...

USN-6467-1 fixed a vulnerability in Kerberos. This update provides the corresponding update for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 23.04. Original advisory details: Robert Morris discovered that Kerberos did not properly handle memory access when processing RPC data through kadmind,...

DEBIAN-CVE-2023-42669

A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in...

CVE-2023-3961

A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call RPC services like SAMR LSA or SPOOLSS, which Samba initiates o...
