CVE-2025-68193

In the Linux kernel, the following vulnerability has been resolved: drm/xe/guc: Add devm release action to safely tear down CT When a buffer object (BO) is allocated with the XE_BO_FLAG_GGTT_INVALIDATE flag, the driver initiates TLB invalidation requests via the CTB mechanism while releasing the BO. However a premature release of the CTB BO can lead to system crashes, as observed in: Oops: Oops: 0000 [#1] SMP NOPTI RIP: 0010:h2g_write+0x2f3/0x7c0 [xe] Call Trace: guc_ct_send_locked+0x8b/0x67
