CVE-2026-80606

In the Linux kernel, the following vulnerability has been resolved: drm/xe/userptr: Hold notifierlock for write on inject test path When CONFIGDRMXEUSERPTRINVALINJECT=y, xeptsvmuserptrprecommit runs vmacheckuserptr with the svm notifierlock taken for read. The test injection causes vmacheckuserpt...
