Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.27/6.2.14/6.3.1 and classified as critical. Affected by this issue is the function ida_alloc of the component media. 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: media: platform: mtk-mdp3: Add missing check and free for ida_alloc Add the check for the return value of the ida_alloc in order to avoid NULL pointer dereference. Moreover, free allocated "ctx->id" if mdp_m2m_open fails later in order to avoid memory leak.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2023-54147 since 12/24/2025. Technical details are known, but there is no available exploit.
