CVE-2026-46197
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: validate SVM ioctl nattr against buffer size Validate nattr field against the buffer size, preventing out-of-bounds buffer access via user-controlled attribute count.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
