Vulnerability from fkie_nvd - Published: 2024-12-29 12:15 - Updated: 2026-06-17 08:12
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
3.3 (Low) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L
Summary
In the Linux kernel, the following vulnerability has been resolved: fbdev: sh7760fb: Fix a possible memory leak in sh7760fb_alloc_mem() When information such as info->screen_base is not ready, calling sh7760fb_free_mem() does not release memory correctly. Call dma_free_coherent() instead.
