An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. CREATE(Triage):(User=admin) CVE-2021-3506 (https://nvd.nist.gov/vuln/detail/CVE-2021-3506)
