The vulnerability stems from an allocation failure at the kernel level during process creation on the DSP. This can lead to memory corruption, potentially allowing an attacker to execute arbitrary code with elevated privileges. While the exact products affected are not specified, the issue resides within Qualcomm DSPs and could impact various devices utilizing these processors. This vulnerability was published on May 4, 2026, and requires patching of the affected DSP firmware to mitigate the risk.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker gains initial access to a device containing a vulnerable Qualcomm DSP.\u003c/li\u003e\n\u003cli\u003eThe attacker triggers a process creation event on the DSP.
