In the Linux kernel, the following vulnerability has been resolved:

can: j1939: transport: j1939 session fresh new(): initialize receive buffer

Zero the allocated buffer in j1939 session fresh new() to ensure it contains no residual data.

While there is a potential performance impact if users allocate maximum sized ETP buffers, most real-world use cases are not noticeably affected since the maximum known buffer size is typically around 65K.
