| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
A race condition exists in the
has locked children() function within the fs/fhandle.c file of the Linux kernel. The may decode fh() function calls has locked children() without acquiring the necessary locks, potentially leading to a system failure. The issue is addressed by renaming the existing has locked children() to has locked children(), making it static, and modifying the callers in fs/namespace.c to use the new function. The has locked children() function is then implemented as a wrapper around has locked children(), invoking the latter under read seqlock excl(&mount lock).Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
