On 64-bit systems,\na value > UINT_MAX is silently truncated when stored.\n\nFix the mismatch by using kstrtouint() instead. This rejects values larger\nthan UINT_MAX at parse time, making truncation impossible. Also add a check\nfor value < 1 to reject the 0-delay case, which would cause the poll work to\nspin without delay and consume 100% CPU.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0e022ee4f8e0dc843ba4c80bb75408a7704279af","tags":[]},{"url":"https://git.kernel.org/stable/c/528052af901d6e6bbfa0e52362a70a58a5dd1e43","tags":[]},{"url":"https://git.kernel.org/stable/c/66cc9dec919dd63d8e4b3d386f7aed3ae684e645","tags":[]},{"url":"https://git.kernel.org/stable/c/ea01c061d839b520f385f112908de1c6e3391327","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
