If smb2_parse_contexts() rejects malformed\ncontext data, SMB2_open() returns without closing the handle, leaving the\nserver-side handle open and num_remote_opens elevated.\n\nClose the handle after a post-CREATE context parsing failure so the error\npath releases the remote resource and balances the open count.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/566820af017e81497fb5e9d3ad6e7ffe2828bc8b","tags":[]},{"url":"https://git.kernel.org/stable/c/80c67cc71d32ccafc89a29b669243b40d81b930f","tags":[]},{"url":"https://git.kernel.org/stable/c/cdb36b09fb1f86d638d0afb44d621ed3f7c1d8eb","tags":[]},{"url":"https://git.kernel.org/stable/c/f09875ff901e933e7b22c913daf51d21e9d93a45","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
