Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An underflow issue exists in the coresight etm4x component. The problem occurs during the initialization or setting of
TRCSEQEVR<n> when the TRCIDR5.NUMSEQSTATE is 0b000, as the code uses drvdata->nrseqstate - 1 in a loop. To resolve this, a nr seq ctrls field and an ETM MAX SEQ TRANSITIONS macro were introduced to decouple the sequence control logic from nrseqstate.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
