**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the parisc component of the Linux kernel, which improperly handles exception conditions. When a trap 7 (Instruction access rights) occurs, the CPU doesn't execute an instruction due to missing execute permissions on the memory region, resulting in a stale IIR value in the cr19 register. This can lead to random old stale values in trap 7 dumps. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
