In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: slab-out-of-bounds read in brcmf_get_assoc_ies() Fix a slab-out-of-bounds read that occurs in kmemdup() called from brcmf_get_assoc_ies(). The bug could occur when assoc_info->req_len, data from a URB provided by a USB device, is bigger than the size of buffer which is defined as WL_EXTRA_BUF_MAX. Add the size check for req_len/resp_len of assoc_info. Found by a modified version of syzkaller.

조치방안
구조화된 수정 버전 값(4.14.315, 4.19.283, 5.4.243, 5.10.180, 5.15.110, 6.1.27, 6.2.14, 6.3.1)은 참고용입니다. 공급사 공식 보안 권고에서 제품·에디션·설치 방식별 수정 기준을 확인한 뒤 적용합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, linux kernel 4.14.315, 4.19.283, 5.4.243, 5.10.180, 5.15.110, 6.1.27, 6.2.14, 6.3.1 기준을 충족하는지 확인합니다. 이어서 메모리 손상 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
