Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel 存在安全漏洞，该漏洞源于直接使用state->fb->obj[0]，而不是通过drm_gem_fb_get_obj函数获取对象，并在对象为空时返回错误代码，以避免使用空的帧缓冲对象。
