CVE-2026-68212

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak exists in the saa7134 video init1() function. The issue occurs because the return values of two saa7134 pgtable alloc() calls are not checked, which can leave the driver with an invalid page table. Furthermore, if vb2 queue init() for the VBI queue fails after the video queue page table has been allocated, the memory is not freed. Since these errors occur during device probing before full registration, the standard cleanup path in saa7134 finidev() is not triggered, resulting in memory leaks and the potential use of uninitialized DMA (Direct Memory Access) resources.

Recommendations Check the return values of both saa7134 pgtable alloc() calls and propagate errors. In the event of a failure in subsequent steps, free the allocated page tables and release control handlers to prevent resource leakage.
