Last modified

CVE-2023-53314 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: fbdev/ep93xx-fb: Do not assign to struct fb_info.dev Do not assing the Linux device to struct fb_info.dev. The call to register_framebuffer() initializes the field to the fbdev device. Drivers should not override its value. Fixes a bug where the driver incorrectly decreases the hardware device's reference counter and leaks the fbdev device. v2: * add Fixes tag (Dan). EPSS estimates a 0.15% chance of exploitation in the next 30 days.
