"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncoresight: etm4x: fix underflow for usage of (nrseqstate - 1)\n\nAccording to IHI006H Embedded Trace Macrocell Architecture\nSpecification[0], TRCSEQEVR<n> is implemented only when\nTRCIDR5.NUMSEQSTATE is 0b100, in which case n ranges from 0 to 2;\notherwise, TRCIDR5.NUMSEQSTATE is 0b000.\n\nIOW, the number of usage in the initialisation or setting\nTRCSEQEVR<n> with drvdata->nrseqstate - 1 in the loop could make\nunderflow issue when TRCIDR5.NUMSEQSTATE is 0b000.\n\nTherefore, introduce nr_seq_ctrls field and untie it from nrseqstate.\nAs part of this introduce ETM_MAX_SEQ_TRANSITIONS macro and\napply nr_seq_ctrls and above macro to TRCSEQEVR<n> relevant fields setup."
