CVE-2026-58975 in Android
Summary
by MITRE • 11/02/2026
In multiple locations, there is a possible out-of-bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

The vulnerability described constitutes an out-of-bounds write condition arising from insufficient validation of input parameters or array indices within the affected software component. In systems programming, such errors typically occur when a function fails to verify that data being written falls within the allocated memory boundaries defined by the application's buffer size. This lack of bounds checking allows malicious actors to overwrite adjacent memory locations with arbitrary values, potentially corrupting critical program structures, control flow pointers, or security-critical variables stored in nearby memory regions. The absence of a missing bounds check is classified under CWE-787: Out-of-bounds Write, which represents one of the most dangerous classes of memory corruption vulnerabilities due to its potential for complete system compromise.
The operational impact of this flaw is severe, specifically enabling local escalation of privilege without requiring additional execution privileges or user interaction. This characteristic significantly lowers the barrier to exploitation, as an attacker does not need social engineering tactics or specific user actions to trigger the vulnerability. Once triggered, the out-of-bounds write can be leveraged to execute arbitrary code with elevated permissions, effectively granting the attacker full control over the affected system. The ability to escalate privileges locally implies that even a low-privileged account on the target machine can achieve administrative rights, thereby bypassing standard access controls and security boundaries designed to isolate user processes from kernel or high-level service operations.
From an offensive security perspective, this vulnerability aligns with MITRE ATT&CK techniques related to privilege escalation and memory corruption exploitation. Attackers may utilize tools such as Metasploit modules specifically crafted for out-of-bounds write exploits to automate the process of gaining root or system-level access. The lack of user interaction further classifies this risk under automated attack vectors, where background processes or services can be targeted without any direct engagement from a human operator. This makes the vulnerability particularly dangerous in environments with multiple users or shared computing resources, as it allows for silent and undetected privilege escalation that could lead to lateral movement within a network if combined with other vulnerabilities.
Mitigation strategies must focus on both immediate remediation and long-term defensive coding practices. The primary solution involves applying vendor-provided patches that correct the logic error by implementing rigorous bounds checking before any memory write operations occur. Developers should ensure that all array indices, buffer sizes, and pointer arithmetic are validated against known limits prior to execution. Beyond patching, organizations should enforce secure development lifecycle protocols that include static application security testing (SAST) tools capable of detecting out-of-bounds writes during the coding phase. Additionally, enabling memory protection mechanisms such as Address Space Layout Randomization (ASLR), Data Execution Prevention (DEP), and stack canisters can mitigate the exploitability of this vulnerability by making it more difficult for attackers to predict target addresses or execute injected code, thereby providing a critical layer of defense in depth even if the underlying flaw remains present.
