However,\nfor the condition of the file being installed in the fixed file table as\nwell as having O_CLOEXEC flag set, the function returns early. At that\npoint, the request doesn't have REQ_F_NEED_CLEANUP flag set. Due to this,\nthe memory for the newly allocated struct filename is not cleaned up,\ncausing a memory leak.\n\nFix this by setting the REQ_F_NEED_CLEANUP for the request just after the\nsuccessful getname() call, so that when the request is torn down, the\nfilename will be cleaned up, along with other resources needing cleanup.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
