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基金会开源的一个操作系统内核。 Linux kernel 6.6.153之前版本、6.12.105之前版本、6.18.46之前版本和7.1.10之前版本存在安全漏洞，该漏洞源于drm/amdgpu在UVD dpb最小尺寸计算中使用了由level派生的最大值，而非解码消息中的实际引用数量。
