CVE-2026-68212

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

media: saa7134: Fix a possible memory leak in saa7134_video_init1

In saa7134_video_init1(), the return value of the first

saa7134_pgtable_alloc() is not checked. If it fails, the function

continues as if successful, leaving the driver with an invalid page

table. Additionally, if vb2_queue_init() for the VBI queue fails after

the video queue page table has been allocated, the allocated memory is

not freed before returning. The second saa7134_pgtable_alloc() also

lacks a return value check. Errors occur during device probing before

the device is fully registered, the normal cleanup path in

saa7134_finidev() is not executed, leading to memory leaks and

potential use of uninitialized DMA resources.

Check the return value of both saa7134_pgtable_alloc() calls and

propagate errors. On failure of any later step, free allocated page

tables to avoid memory leaks. Ensure control handlers are also

released on error to prevent

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
