CVE-2012-2674: n/a vulnerability

CVE-2012-2674: Multiple integer overflows in the (1) chk_malloc, (2) leak_malloc, and (3) leak_memalign functions in libc/...

Multiple integer overflows in the (1) chk_malloc, (2) leak_malloc, and (3) leak_memalign functions in libc/bionic/malloc_debug_leak.c in Bionic (libc) for Android, when libc.debug.malloc is set, make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which causes less memory to be allocated than expected.

Security readout for executives and security teams

This issue affects Android's Bionic libc debug malloc leak tracking code when libc.debug.malloc is enabled. A very large requested allocation size can wrap around internally, causing too little memory to be allocated and creating conditions for memory corruption. Exposure appears limited to Android/Bionic environments using the affected malloc_debug_leak code with libc.debug.malloc enabled. The source bundle does not provide affected Android version ranges, device lists, or distribution-specific advisories. Treat this as targeted maintenance risk for Android-based products, not a broad emergency from the supplied evidence. Prioritize inventory and patch verification for custom, legacy, or debug-enabled builds. Mitigation focus: Check Android vendor guidance for the relevant Bionic branch or device build.; Apply the vendor-approved Bionic upstream patch where applicable.; Ensure libc.debug.malloc is not enabled in production builds..
