Dear Kernel Maintainers, I am writing to report a potential vulnerability identified in the upstream Linux Kernel version v6.6, corresponding to the following commit in the mainline repository: Git Commit: ffc253263a1375a65fa6c9f62a893e9767fbebfa (tag: v6.6) This issue was discovered during the testing of the Android 15 AOSP kernel, which is based on Linux kernel version 6.6, specifically from the AOSP kernel branch: AOSP kernel branch: android15-6.6 Manifest path: kernel/common.git Source URL: https://android.googlesource.com/kernel/common/+/refs/heads/android15-6.6 Although this kernel branch is used in Android 15 development, its base is aligned with the upstream Linux v6.6 release. I observed this issue while conducting stability and fuzzing tests on the Android 15 platform and identified that the root cause lies in the upstream codebase. Bug Location: remove_proc_entry+0x194/0x334 fs/proc/generic.c:711 Bug Report: https://hastebin.com/share/sinejizobu.css Entire Log: https://pastebin.com/J0p8J9W5 Thank you very much for your time and attention. I sincerely apologize that I am currently unable to provide a reproducer for this issue. However, I am actively working on reproducing the problem, and I will make sure to share any findings or reproducing steps with you as soon as they are available. I greatly appreciate your efforts in maintaining the Linux kernel and your attention to this matter. Best regards, Luka
