Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.16.0-rc4-next-20250704-06511-gff0e002d480a
Description
The Linux kernel contains an issue within the nxp imx8-isi m2m subsystem. An imbalance in streamon/streamoff calls, such as exiting an application with Ctrl+C during streaming, can prevent the m2m usage count from reaching zero, leading to memory leaks and preventing the ISI channel from being freed. Additionally, if the input line width exceeds 2K, a warning is triggered. The issue is addressed by moving streaming preparation and cleanup to the vb2 .prepare streaming() and .unprepare streaming() operations.
Recommendations
Update to a version later than 6.16.0-rc4-next-20250704-06511-gff0e002d480a.
