From 80a45f078fcf1b7157535dcbf07d210ac2c7cd82 Mon Sep 17 00:00:00 2001 From: Yi-an Chen Date: Tue, 20 Feb 2024 04:34:57 +0000 Subject: [PATCH] Fix error handling for non-dynamic permissions We only allow removing dynamic permissions. When removePermission() is called for a non-dynamic permission, in addition to logging it, we should also return early to avoid the removePermission() call. Test: manual Bug: 321555066 Fixes: 321711213 (cherry picked from https://googleplex-android-review.googlesource.com/q/commit:2b5d63b64b2b8208ccc4f62eac3d8962f981dbf8) Merged-In: I7336f2fc78804f26e4b2a329870ecdea776595d8 Change-Id: I7336f2fc78804f26e4b2a329870ecdea776595d8 --- .../android/server/pm/permission/PermissionManagerService.java | 1 + 1 file changed, 1 insertion(+) diff --git a/services/core/java/com/android/server/pm/permission/PermissionManagerService.java b/services/core/java/com/android/server/pm/permission/PermissionManagerService.java index f83c3d5145cc7..eb27a13523baf 100644 --- a/services/core/java/com/android/server/pm/permission/PermissionManagerService.java +++ b/services/core/java/com/android/server/pm/permission/PermissionManagerService.java @@ -645,6 +645,7 @@ public void removePermission(String permName) { // TODO: switch this back to SecurityException Slog.wtf(TAG, "Not allowed to modify non-dynamic permission " + permName); + return; } mSettings.removePermissionLocked(permName); mPackageManagerInt.writeSettings(false);
