  "details": "In the Linux kernel, the following vulnerability has been resolved:  iommu/tegra241-cmdqv: Fix VINTF0 leak on the init-failure path  tegra241_cmdqv_init_structures() allocates VINTF0 with kzalloc_obj(), inits it, and preallocates its logical VCMDQs. Two of its error paths leak.  When tegra241_cmdqv_init_vintf() fails it returns before VINTF0 reaches the cmdqv-\u003evintfs[] array, so the devres unwind on probe failure cannot reach it; free it directly there.  A later VCMDQ preallocation failure instead leaves VINTF0 published, and so this time the unwind does reach tegra241_cmdqv_remove_vintf(), which then frees it from vintf-\u003ehyp_own. But tegra241_vintf_hw_init() sets that flag only afterward, from a HW read-back, so the still-uninited VINTF0 reads as guest-owned and leaks, with mutex_destroy() and ida_destroy() run on fields it never set up.  Decide ownership from vintf-\u003eidx instead, the index assigned when its id is allocated: idx 0 is the kernel-owned VINTF0, while idx \u003e= 1 marks a guest VINTF. So the in-kernel free decision in tegra241_cmdqv_remove_vintf() and tegra241_vintf_free_lvcmdq() now keys on idx too, and hyp_own stays a pure HW-readback state.",
