CVE-2023-54099

11
FAUCET Score

CVE-2023-54099 is a vulnerability in the Linux kernel's filesystem remounting process. It allows for a race condition where user-space writes can occur immediately after a filesystem is reconfigured from read-only to read-write, but before the filesystem is fully prepared to handle them. This could lead to data corruption or system instability, particularly for filesystems like ext4. While no CVSS score is provided, its FAUCET Risk Score is 7/100, indicating a low severity. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this vulnerability.
