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.\n\n## Affected\n\n- `OxygenOS >= 16.1.0 < 16.1.10.500`\n- `OxygenOS >= 16.0.0 < 16.0.5.1200`\n- `OxygenOS >= 15.0.0 < 15.0.0.2000`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":46.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
