In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: edma: Fix memory allocation size for queue_priority_map Fix a critical memory allocation bug in edma_setup_from_hw() where queue_priority_map was allocated with insufficient memory. The code declared queue_priority_map as s8 (*)[2] (pointer to array of 2 s8), but allocated memory using sizeof(s8) instead of the correct size. This caused out-of-bounds memory writes when accessing: queue_priority_map[i][0] = i; queue_priority_map[i][1] = i; The bug manifested as kernel crashes with "Oops - undefined instruction...

조치방안
제3자 참조와 수정 버전 값(5.4.300, 5.10.245, 5.15.194, 6.1.153, 6.6.107, 6.12.48, 6.16.8)은 보조 근거로만 사용하고, 공급사 공식 보안 권고에서 조치 기준을 재확인합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, linux kernel, debian linux 5.4.300, 5.10.245, 5.15.194, 6.1.153, 6.6.107, 6.12.48, 6.16.8 기준을 충족하는지 확인합니다. 이어서 메모리 손상 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
