"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: Fix acl.sd_buf memory leak and invalid sd_size error handling\n\n1. When ndr_decode_v4_ntacl() fails, the code jumped to free_n_data\n which only freed n.data, skipping kfree(acl.sd_buf) and leaking\n the buffer. Zero-initialize struct xattr_ntacl acl, reorder error\n labels to out_free to release acl.sd_buf on all error paths.\n\n2. if (acl.sd_size < sizeof(struct smb_ntsd)) is true, original code\n returned success without freeing sd_buf and left stale *pntsd.\n Set rc = -EINVAL before jumping to out_free to return error code and\n free buffer."
