[PATCH OLK-6.6] media: vimc: skip .s_stream() for stopped entities
by Zheng Xinyu 24 Apr '25

24 Apr '25

From: Nikita Zhandarovich <n.zhandarovich(a)fintech.ru> mainline inclusion from mainline-v6.15-rc1 commit 36cef585e2a31e4ddf33a004b0584a7a572246de category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC1QQ2 CVE: CVE-2025-22028 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Syzbot reported [1] a warning prompted by a check in call_s_stream() that checks whether .s_stream() operation is warranted for unstarted or stopped subdevs. Add a simple fix in vimc_streamer_pipeline_terminate() ensuring that entities skip a call to .s_stream() unless they have been previously properly started.
