Overview
About vulnerability
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.
