      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\narm64: errata: Mitigate TLBI errata on various Arm CPUs\n\nA number of CPUs developed by Arm suffer from errata whereby a broadcast\nTLBI;DSB sequence may complete before the global observation of writes\nwhich are translated by an affected TLB entry.\n\nThese errata ONLY affect the completion of memory accesses which have\nbeen translated by an invalidated TLB entry, and these errata DO NOT\naffect the actual invalidation of TLB entries. TLB entries are removed\ncorrectly.\n\nThis issue has been assigned CVE ID CVE-2025-10263.\n\nTo mitigate this issue, Arm recommends that software follows any\naffected TLBI;DSB sequence with an additional TLBI;DSB, which will\nensure that all memory write effects affected by the first TLBI have\nbeen globally observed. The additional TLBI can use any operation that\nis broadcast to affected CPUs, and the additional DSB can use any option\nthat is sufficient to complete the additional TLBI.\n\nThe ARM64_WORKAROUND_REPEAT_TLBI workaround is sufficient to mitigate\nthe issue. Enable this workaround for affected CPUs, and update the\nsilicon errata documentation accordingly.\n\nNote that due to the manner in which Arm develops IP and tracks errata,\nsome CPUs share a common erratum number.",
