CVE-2024-40901

21
FAUCET Score

CVE-2024-40901 is a high-severity out-of-bounds write vulnerability in the Linux kernel's mpt3sas SCSI driver. It occurs when test_bit() or set_bit() functions operate on a single word, potentially exceeding memory boundaries and leading to a KASAN-detected slab-out-of-bounds error. With a CVSS score of 7.8 (HIGH), this vulnerability has a local attack vector, low attack complexity, and can result in high impacts to confidentiality, integrity, and availability. The issue stems from insufficient memory allocation for bitwise operations. Currently, there is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE. It is not listed on CISA's KEV catalog.
