"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe/guc: Add devm release action to safely tear down CT\n\nWhen a buffer object (BO) is allocated with the XE_BO_FLAG_GGTT_INVALIDATE\nflag, the driver initiates TLB invalidation requests via the CTB mechanism\nwhile releasing the BO. However a premature release of the CTB BO can lead\nto system crashes, as observed in:\n\nOops: Oops: 0000 [#1] SMP NOPTI\nRIP: 0010:h2g_write+0x2f3/0x7c0 [xe]\nCall Trace:\n guc_ct_send_locked+0x8b/0x670 [xe]\n xe_guc_ct_send_locked+0x19/0x60 [xe]\n send_tlb_invalidation+0xb4/0x460 [xe]\n xe_gt_tlb_invalidation_ggtt+0x15e/0x2e0 [xe]\n ggtt_invalidate_gt_tlb.part.0+0x16/0x90 [xe]\n ggtt_node_remove+0x110/0x140 [xe]\n xe_ggtt_node_remove+0x40/0xa0 [xe]\n xe_ggtt_remove_bo+0x87/0x250 [xe]\n\nIntroduce a devm-managed release action during xe_guc_ct_init() and\nxe_guc_ct_init_post_hwconfig() to ensure proper CTB disablement before\nresource deallocation, preventing the use-after-free scenario."
