What is CVE-2026-43145?
CVE-2026-43145 is a medium-severity vulnerability in Linux kernel, published on 6 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
