The olc2 logging HAL exposes a binder method that fork()'s and calls execl(\"/vendor/bin/sh\", \"sh\", \"-c\", cmd, NULL) with a caller-supplied command string. The only authorization check is getCallingUid() == 0. Because SELinux policy grants binder access to this HAL to a wide client attribute, any uid-0 process in any of those domains (including dumpstate, which is reachable from an unprivileged app via Vulnerability 1) obtains arbitrary command execution. The spawned shell lands in u:r:vendor_qti_init_shell:s0 SELinux context via a policy type_transition, a domain holding all Linux capabilities. This issue affects OxygenOS: from 16.1.0 before 16.1.10.500, from 16.0.0 before 16.0.5.1200, and from 15.0.0 before 15.0.0.2000.","published":"2026-10-21T09:17:08.000Z","lastModified":"2026-10-22T16:58:52.000Z","status":"Deferred","sourceIdentifier":"a6d3dc9e-0591-4a13-bce7-0f5b31ff6158","cvss":{"version":"4.0","score":8.4,"severity":"HIGH","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-749","CWE-863"],"affected":[],"epss":{"score":0.00308,"percentile":0.23379,"date":"2026-10-26","history":[{"date":"2026-10-21","score":0.00128,"percentile":0.02216}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.31%).
