Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 5.10.120/5.15.45/5.17.13/5.18.2. Affected by this issue is the function platform_get_resource of the component cadence_nand_dt_probe. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to 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. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: fix possible null-ptr-deref in cadence_nand_dt_probe() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2022-49494 since 02/26/2025. Technical details are known, but there is no available exploit.

Upgrading to version 5.10.121, 5.15.46, 5.17.14 or 5.18.3 eliminates this vulnerability.
