Title
remoteproc: imx_rproc: Fix invalid loaded resource table detection
Summary
In the Linux kernel, the following vulnerability has been resolved: remoteproc: imx_rproc: Fix invalid loaded resource table detection imx_rproc_elf_find_loaded_rsc_table() may incorrectly report a loaded resource table even when the current firmware does not provide one. When the device tree contains a "rsc-table" entry, priv->rsc_table is non-NULL and denotes where a resource table would be located if one is present in memory. However, when the current firmware has no resource table, rproc->table_ptr is NULL. The function still returns priv->rsc_table, and the remoteproc core interprets this as a valid loaded resource table. Fix this by returning NULL from imx_rproc_elf_find_loaded_rsc_table() when there is no resource table for the current firmware (i.e. when rproc->table_ptr is NULL). This aligns the function's semantics with the remoteproc core: a loaded resource table is only reported when a valid table_ptr exists. With this change, starting firmware without a resource table no longer triggers a crash.

However, when the current firmware has no resource\\ntable, rproc-\u003etable_ptr is NULL. The function still returns\\npriv-\u003ersc_table, and the remoteproc core interprets this as a valid loaded\\nresource table.\\n\\nFix this by returning NULL from imx_rproc_elf_find_loaded_rsc_table() when\\nthere is no resource table for the current firmware (i.e. when\\nrproc-\u003etable_ptr is NULL). This aligns the function\u0027s semantics with the\\nremoteproc core: a loaded resource table is only reported when a valid\\ntable_ptr exists.\\n\\nWith this change, starting firmware without a
