A potential memory leak vulnerability in the Linux kernel's Radeon framebuffer driver was fixed. The issue occurred in the radeonfb_pci_register() function, where allocated memory for video modes was not freed on error paths. This could lead to resource leakage if errors occur during mode registration. The fix involves properly freeing the allocated memory by calling fb_destroy_modelist().
AI Analysis
Technical Summary
The vulnerability in the Linux kernel affects the Radeon framebuffer driver (fbdev). Specifically, the function radeonfb_pci_register() allocates memory for a list of video modes via radeon_check_modes() and fb_add_videomode(). However, if an error occurs after allocation, the memory appended to info->modelist is not freed, causing a potential memory leak. The patch addresses this by ensuring fb_destroy_modelist() is called to free the allocated memory on error paths.
Potential Impact
The impact is a potential memory leak in the Radeon framebuffer driver within the Linux kernel. This could lead to increased memory usage and possible resource exhaustion over time if the error condition is triggered repeatedly. There is no indication of direct code execution or privilege escalation from this vulnerability.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to address this memory leak by properly freeing allocated memory on error paths in radeonfb_pci_register(). Users should update to the fixed kernel version once available. Patch status is not explicitly confirmed in the provided data; check the vendor or Linux kernel advisory for the exact fixed versions and update instructions.
