Description OSIDB Bzimport 2025-06-18 12:14:10 UTC 
In the Linux kernel, the following vulnerability has been resolved:

misc: fastrpc: fix memory corruption on probe

Add the missing sanity check on the probed-session count to avoid
corrupting memory beyond the fixed-size slab-allocated session array
when there are more than FASTRPC_MAX_SESSIONS sessions defined in the
devicetree.
