Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 6.1.102/6.6.43/6.10.2. This vulnerability affects the function imx_rproc_addr_init of the component remoteproc. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: remoteproc: imx_rproc: Skip over memory region when node value is NULL In imx_rproc_addr_init() "nph = of_count_phandle_with_args()" just counts number of phandles. But phandles may be empty. So of_parse_phandle() in the parsing loop (0 < a < nph) may return NULL which is later dereferenced. Adjust this issue by adding NULL-return check. Found by Linux Verification Center (linuxtesting.org) with SVACE. [Fixed title to fit within the prescribed 70-75 charcters]

The advisory is available at git.kernel.org. This vulnerability was named CVE-2024-43860 since 08/17/2024. Technical details are known, but there is no available exploit.
