Apple has acknowledged a hardware-based security vulnerability affecting several older iPhone models, stating a fix is not currently available. The flaw potentially allows attackers to compromise device security. Affected models include those predating iPhone 8, though specific models were not detailed in initial reports. Apple advises users of these devices to exercise caution and limit potential exposure. The company emphasized the vulnerability stems from the hardware itself, making a software update impossible to resolve. While Apple hasn’t disclosed the extent of the risk, security experts suggest the flaw could allow for malicious code execution. Users are encouraged to practice general cybersecurity hygiene, such as avoiding suspicious links and software.
