Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel related to filesystem remounting. Specifically, the code responsible for reconfiguring or remounting filesystems does not adequately protect against racing writes during the transition from read-only to read-write mode. This can occur when clearing the
SB RDONLY flag, potentially allowing userspace writes to begin before the filesystem is fully prepared to accept them. This issue was identified through fuzzing and could be exploited. The fix involves using the sb->s readonly remount flag to prevent these racing writes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
