CVE-2026-94030: Integer Overflow in SerenityOS
CVE-2026-94030 is an integer overflow vulnerability in SerenityOS affecting the decode_bmp_pixel_data function in the LibGfx component. The vulnerability arises from manipulation of the height argument, potentially leading to an integer overflow. Exploitation is possible remotely but considered difficult with high attack complexity. A minimal proof-of-concept exists, though evidence of a fully exploitable defect is limited. SerenityOS uses a rolling release model, so specific affected versions are not defined. A patch identified by commit 007041bb2dd6d140c9e707caddfb0a49ecf96469 is recommended to remediate this issue. The CVSS 4.0 score rates this vulnerability as low severity.
AI Analysis
Technical Summary
This vulnerability in SerenityOS up to commit 3d83e4509fd20d7438e1ae8470ffe668c136229c involves an integer overflow in the decode_bmp_pixel_data function within the LibGfx component. The flaw is triggered by manipulation of the height parameter, which can cause an integer overflow condition. The vulnerability can be exploited remotely but requires high attack complexity and user interaction, with no privileges needed. A minimal 55-byte proof-of-concept was created via fuzz testing, but the evidence for a practical exploit is limited. The product's rolling release strategy means no fixed version numbers are provided. A patch with commit ID 007041bb2dd6d140c9e707caddfb0a49ecf96469 addresses the issue.
Potential Impact
The integer overflow could potentially lead to memory corruption or other unintended behavior when processing BMP images, but the low CVSS score and high attack complexity indicate limited impact. Exploitation requires remote access and user interaction, and no known exploits are currently in the wild. The vulnerability's practical exploitability appears low based on available evidence.
Mitigation Recommendations
A patch identified by commit 007041bb2dd6d140c9e707caddfb0a49ecf96469 is available and should be applied to remediate this vulnerability. Since SerenityOS follows a rolling release model, users should update to the latest version containing this patch. No additional mitigation steps are indicated.
