CVE-2026-43202 Details
Description
In the Linux kernel, the following vulnerability has been resolved: fbdev: vt8500lcdfb: fix missing dma_free_coherent() fbi->fb.screen_buffer is allocated with dma_alloc_coherent() but is not freed if the error path is reached.
A vulnerability exists in the Linux kernel's framebuffer device (fbdev) driver for the vt8500lcdfb. The issue arises because the framebuffer's screen buffer is allocated using dma_alloc_coherent() but is not properly deallocated if an error occurs during the initialization process. This oversight can lead to memory leaks.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
