CVE-2023-44128: 
NixOS vulnerability analysis and mitigation

A vulnerability was discovered in LG's LGInstallService ("com.lge.lginstallservies") app, identified as CVE-2023-44128. The vulnerability affects Android devices running versions 4.0 through 13.0 and specific LG devices like the V60 ThinQ 5G. The issue was disclosed and initially analyzed by NIST on September 27, 2023 (NVD).

The vulnerability exists in the exported "com.lge.lginstallservies.InstallService" service that exposes an AIDL interface. The issue involves a Time-of-check Time-of-use (TOCTOU) Race Condition (CWE-367) where all "installPackage*" methods ultimately call the "installPackageVerify()" method. This method performs signature validation after the delete file operation, creating a security weakness. The vulnerability has received a CVSS v3.1 base score of 3.6 (LOW) from NIST with vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L, while LG Electronics assessed it at 5.0 (MEDIUM) with vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:L (NVD).

The vulnerability allows an attacker to delete arbitrary files by manipulating conditions so that the security check is never performed. This can lead to unauthorized file deletion on affected devices (NVD).

LG Electronics has acknowledged the vulnerability and provided information through their security bulletin. Users should refer to LG's security advisory for specific mitigation steps (LG Security).
