ما الذي حدث
Bitdefender researchers found that two Android libraries interpret ZIP compression methods inconsistently. A specially crafted APK can bypass size checks, map a file into an unallocated memory region, and cause the core system_server process to read invalid memory, raising a SIGBUS and crashing. The crash triggers an automatic restart, leading to a persistent boot loop that repeats over 100 times on a Pixel 10 with Android 17. The malicious app requires no permissions and does not need to be launched. Google has been aware since August 2024 but has not released a patch, classifying the report as “not reproducible.”
