Description OSIDB Bzimport 2026-08-28 07:43:03 UTC
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.
