CVE-2026-43145
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.
